Also tried a 16x6” chrome wheel l had as a spare with a 265/75/16 muddy
Think lm liking the idea of going for the 255/85/16 Yokohama G003 mud tyres on the 16” wagon style wheels.

Love the look of this cruiser with the same wheel and tyre set up.
Got a lead on 3 other rims, so just need a 5th for the spare. Going to have them blasted and powder coated black.
New rims from Toyota were $360ea out of Japan😬

Found a guy near me selling 6 rims which seemed to be the wagon style wheels, 4 were painted black and dated 16x6” 90 build and two chrome wheels, one which is the chrome split. So for $80 we have 5 new rims and a 16x5.5 chrome split which l will sell off. Cleaned them up and did a trial fit, tyres are 235/85/16 but will go for the bigger 255/85/16 to fill out the wheel arches better.

A long time ago l built a rear diff assembly from my 60 series donor to fit the rear of the 40 series but now l have decided to go with the standard look without flares the 60 diff is pushing the tyres out of the guards slightly.
So l remembered I had a spare diff housing that came with the HJ47 and the spare 40 ute tub.
So a quick measure with the tape showed it was a 40 series full floating rear. It looked solid but had a lot of rust even in the inside.
Several hours later with a wire wheel and stripping discs it seem to clean up nice

Final clean up, think this will do it

As this housing was bare l will have to swap everything over, lucky for me l have anther complete spare rear 60 series housing that will sacrifice its parts. So starting stripping all the parts of the 60 diff, only problem will be the long side axle will have to come from a 40 series or possibly a 70 series?
Can anyone confirm if a 70 series will work?
Pulled the centre out and found the backlash was way too much so thought l may as well go over the centre, after readjusting the back lash l found the runout on the crown wheel was out of spec. Runout measured 0.19mm, max is 0.10mm. This was causing the backlash clearance to change as l measured it😔
So will need to swap out the carrier for another, to the spare parts cupboard we go.
Measuring the backlash

Tool l made to adjust the carrier bearings, don’t mind the bogger welds

Got some epoxy primer and black top coat on the rear diff housing. Have a rear diff centre from my 80 series that l pulled out when l fitted the airlocker so might put that centre in if the flange suits the tail shaft pattern. Will still fix up the other centre so l have a spare, hoping to just fit some new carrier bearings and call it done with the other crown wheel centre.

Set up the 60 series centre with another carrier that l had and preloaded the carrier bearings. Used 80ftlbs as they were used bearings l swapped over and set the backlash. This time all the readings were consistent and run out of the crown wheel carrier was in specs. Checked the pattern with some paint and all looks good for a used gear set, hopefully quiet but probably won’t here it in a soft top anyway.

Then l remembered l had another diff centre from my 80 series with a LSD and thought l would check the pattern and carrier bearing preload on that, maybe an LSD would be better in the shorty🤔
I removed this from the 80 to fit a locker a while ago, it had no noises or issues.
Tensioned up the bearings and ran a pattern , seems the coast side is a bit too much towards the toe? Not sure if it needs some more backlash to bring in to the heel a bit more.

Fitted up the 80 series diff centre and started to clean up the backing plates and fit the new brakes. All new springs for the brake assembly and ordered some more parts, mmmmm parts🤤
Looked around for a long side 40 series axle 2nd hand, a 70 series is also the same for anyone looking for one, but ended up buying an aftermarket one new for a decent price. At least l know the splines wont be worn like all the used ones l looked at. Cut down the 60 series diff brake line to suit the shorter 40 housing, my housing was bare so using all the 60 stuff l have for it.

So waiting on the axle, handbrake boots for the pivot assembly and some more rear wheel bearings as l want to have all new bearings fitted.
Also got a BJ42 rear handbrake cable coming with some 80 series parts l ordered.
l did notice the rear spring plate mounts will need to have the lower shock mount in them as the 71 has the mount built into the spring perch, hopefully have some 60 series ones in the spare parts pile, otherwise l will have to try and find later 40 series ones?
Other issue will be the 80 series diff flange has a different bolt pattern to the 60 series shaft but l have a few spare shafts that might sort that issue out.

Assembled the rest on the rear brakes and fitted the other hub with new bearings. Ripped out the modified 60 diff l had fitted and swapped in the 40 diff assembly.

Then found another tailshaft with the right bolt pattern to suit my 80 series diff pinion flange. Decided the best thing to do was swap the rear half of the tailshaft yokes over. Managed to reuse the uni joints which were still good. As you can see in the picture the flange bolt pattern differance. Cleaned up sandblasted yoke suits the 80 series

So my son and his girlfriend want me to drive them to their year 12 graduation in the shorty so been given a dead line to get this thing done. Have her some fresh oil and filter and a bit of stop smoke, been a while since it had a oil change and blew a little bit of smoke. Old 2f used to run on lpg and suspect it has worn valve stem seals.
Got the front headlight bezel mounted up, going to make a hit list for registration.

Also scored a swb roof and sides from local guy just looking to get rid of it. Fibreglass is buggered but the gutter is in good condition and the sides are still saveable. I also have another fibreglass roof in fair condition so might be able to make a good one, or chop this for my extra cab ute build🤔
Gave it a quick gernie and a little bit of a panel beating to see what l have to work with.

Cleaned up the front indicator lenses and fitted the lights, made a thin rubber gasket for them to mount onto the guards.
Also cleaned up the drivers seat frame and my custom seat slides got a sand blast and paint, looking at getting the seats trimmed later down the road.
How they were and after a clean up

I did plan on getting the seats and back metal trim powder coated but due to time restraints l cleaned them up with CLR then rust converter. Will put some penetrol on them to preserve the patina look. Got some stainless steel cups and screws to replace the original rusty screws and hardware. Will need a few more for the back and will order some more for the bottoms on the seat as well.
Seat slides and frame painted and fitted.

Freed up the seized choke cable and got it working. Stripped the light and wiper switches for a clean up and started to tidy up the wiring. Then refitted the indicator linkage and plugged in the bullet terminals to the corresponding wire colours and that’s when the problems started😂
Tried to find a wiring diagram for a 71 and everyone l found has a hazard switch connected, mine never had a switch but seems it has a plug. Then came across what appears to be 2 flasher cans, think one is for the indicators and the other for the hazards🤔🤷🏻‍♂️
Have to hook up and check the wiring for the front lights and indicators tomorrow.

Be very careful pulling apart apart a 50 year old switch, mine got stuck on the plug and l had to get a little forceful to get it off that's why the board looks a little damaged. Looks like new switches are still available so l will order a new one.

Stripped down the indicator switch as well. Cleaned the contacts and regressed the slides. Thinking l should put some dielectric grease or similar on the contact surfaces to stop corrosion. Anyone recommend a product?

Cleaned up contacts before reassembly. Also made a new earth cable from the motor to the chassis as l know earthing issues can cause a lot of problems.

Ordered the Yokohama G003 tyres and got wheels off to be powder coated satin black. While l wait for them to come back l bought some 79 series leaf spring u bolt plates. These will replace my ones with no lower shock mounts. They remove these from the brand new 79 series to do a rear coil conversion so got these for $50. Only issue is you need to have a rear shock that suits the lower 19mm OD mounting. Looks like 75 series rear shocks should fit and do something with the 16mm OD top mount.
Old vs new

Fitted the old shocks for now which are still good but will order all new ones later down the track. Managed to squeeze the old bushes over the larger pins.
Have made a diff mount for the handbrake cable, still need to do another bracket above the diff centre then work out how to graft the early and late cables together🤔

Slowly moving forward, trying to find a missing body mount with no luck. Then moved onto fitting the rear badges and looks like the mounting bolts don’t line up😔 l will try to find my old one and double checked the part number and it seems right, manufacturers fault? Not sure but l don’t think it’s going to fit the original body holes. Anyone have a measurement for me to compare?
After measuring the differance it appears to be 4-5mm between the mounts, maybe a small adjustment maybe required🙄
