Was able to layout spots for 3 USB/12V plugs on the lower portion of the dash. Drilled the holes and added 10-24 threaded nutserts

This M715 never had grill of any sort, just a great gaping hole open to the radiator. Maybe the grill was lost years ago, who knows 🤷‍♂️ Wanting to avoid jamming a stick right through a very expensive radiator, I picked up some 316 stainless expanded metal. Then, I replaced the 5 factory sheet metal tabs with much heavier 1/8” units

1641613301140.webp


Formed the expanded metal a bit with a sanding wheel, TIG welded some stainless 3/8-16 nuts on the backside and…

1641613354619.webp


It came out pretty well. The metal has a bit of a curvature to it when the fasteners get tightened up and it’s VERY solid

It's NP205 time.... Thx for the photo bombing Kaiser!

1641613525442.webp


Fortunately Mark and I label all this stuff when it comes apart. Years later I’d have no clue what it came out of. This 205 is from an ‘89 Chevrolet K30 crewcab truck from Fairbanks, AK. It was a former Alyeska Pipeline truck with a 6.2 liter diesel. This case has the more desirable large input bearing

1641613577797.webp


Oil looked good....

1641613622265.webp


It’s apart. Internals look great but for some odd reason the inside of the 205 case is rusty. Easy fix, I’ll take that over junk internals

1641613664272.webp


1641613704417.webp
 
Washed...

1641613771266.webp


1641613844848.webp


Found the factory tag, looks like it might actually be an ‘84 case that had been swapped into the ‘89 truck at some point. Either way, it still has the large 90mm input bearing

1641613910984.webp


Blasted and nearly ready for paint and reassembly. Flat surfaces got smoothed with a DA

1641613983279.webp


1641614004738.webp


AND rust free internally

1641614040993.webp
 
So here’s some input shaft comparison. The middle shaft is a new “Fat Shaft” from Off-Road Design. Left shaft is from this case and the right shaft is from a different 205 altogether. The left shaft is internally splined. Note that the ORD shaft is far bigger and more robust. And this is a fully synchronized case which I don't actually want. I'll be swapping out all the front output shaft components

1641614147399.webp


Another ORD shaft on top, OEM 205 on the bottom. The goal is brute strength, all the internal shafts are being replaced/upgraded

Shifting gears a bit…

I’ve been putting off the sheet metal and rocker replacement because I dislike body work so much. Time to just get it over with

It’s pretty hard to find panels for this vintage FSJ. We had ordered rockers from BJ’s off-road but the fitment was TERRIBLE. None of the contours matched the original lines and they are made in Taiwan. After going back and forth with them, they admitted they were aware of some fitment problems and were “working on it”. Over 6 months later with no progress, my buddy just bent some up locally. I still needed to use the cab corner and pillar from BJ’s tho, fortunately, those pieces were ballpark close. No where near great, but close enough after cutting some of the bends and contours out

Front panel support...

1641614359128.webp


Rear rocker cut down to match interior panel contours

1641614411040.webp


“B” pillar cut down to size, fitted and tack welded

1641614451858.webp


Fully welded and sanded/blended down at the seams

1641614489769.webp


Welded rocker, I’ll add the cab corner later

1641614534164.webp
 
Got a bit closer today and managed to finesse the driver cab corner into place!

Reinforced the interior of the “B” pillar

1641614618490.webp


Made supports for the upper part of the cab corner

1641614652861.webp


One example of many regarding how poorly these panels fit. The original 90 degree break in the sheet metal left the panel WAY too long to correctly line up with the flange inside the cab. So, you cut the panel down and weld a length of steel in lengthwise so things actually line up

1641614682942.webp
 
It’s in, not fully welded yet

Correctly getting it to line up as best as possible required my wife pushing the hell out of it in several places as I tacked it into place. The Taiwanese steel is also a joy to weld on, just full of impurities :(

Moving on to something less tedious than sheet metal work.

1.5” spacers arrived from Wheeladapter.com These are machined from Timken steel and use a 10.9 wheel stud. MUCH stronger than OEM.

These were needed to give us a bit more clearance at extreme articulation as the tire is quite close to the coil over

1641614861800.webp


1641614884598.webp


The fit was excellent, these are a very quality spacer

1641614921421.webp
 
Monkeying with the exhaust again.

Added quick disconnect flanges to all 3 ends of the cross over pipe

1641614986407.webp


Stainless flex joint and Borla muffler…

1641615040789.webp


Snaking it through the cross member, this is a full 3” exhaust from the headers back

1641615075741.webp


Stainless hangers with insulators, again used weld in nutserts to mount them

1641615110001.webp


2nd Borla muffler and a bit of tube, this gets the exhaust out and over the rear axle with room to spare at full bump. Little more exhaust to go tho

1641615152750.webp
 
Got the whole exhaust mess in. It’s tacked and has support brackets, just needs to come out for final welding

LOTS of bends. This piece gets the exhaust up and over the rear frame rail

1641615235470.webp


3rd Borla muffler, right under the bed and just behind the 14B axle. 3 mufflers? Since neither one of us are 16 years old anymore I’d rather hear the conversation than listen to the exhaust drone away. It’ll be stealthy, HA! If I sneak up on you out on the trail you’ll know why 🙄

1641615275309.webp


Rear dump exits just behind the passenger rear tire

1641615305475.webp


1641615342273.webp


It’s up and out of the way, it’ll be mostly covered when I add the rear bumper extensions

1641615380658.webp
 
Moving on to finishing out the rear suspension. Need to set the King bumpstops in for good and determine the limit strap length

This is full stuff driver with the passenger side coil over fully dropped/extended. Essentially the wheel hub is on the floor

1641615441068.webp


Perfect fit!!

1641615477866.webp


Blue towel roll is simulating the coil over, it’s the same diameter. Very close clearance to both the tub, fender and coil over

1641615516092.webp


1641615547835.webp
 
Rear bumps are in, what a pain. Apparently it’s a well documented issue that the King bumpstop cans distort when they are welded, which makes it impossible to get the bump in and out of the can. After fighting this for a bit, I had a friend machine up an aluminum slug to help keep the can round

1641615630901.webp


1641615651128.webp


1641615675360.webp
 
Full droop. Quite a bit

1641615733610.webp


1641615761923.webp


Ride height. About 1” of up travel before the axle begins to hit the bump. Bumps have 2.5” of travel

1641615808373.webp
 
Couple of small things

Mounted the Hole Herse floor switch for the headlight High/Low beams

1641615878053.webp


Fully waterproof and tucked up behind the inner fender

1641615982553.webp
 
Cut up some chunks of DOM to make rear frame reliefs. At max droop, the coils were JUST making contact with the outside of the frame

1641616037082.webp


1641616069953.webp


Of course there just had to be a nasty old chunk of frame or leaf spring support right where it needed to go 🙄

1641616108419.webp


Relief pieces, they are .120 wall

1641616144148.webp


1641616175847.webp


Done on the driver side, passenger side needs the same

1641616207559.webp
 
Got the passenger side coil notch completed today

Blasted through the frame….

1641616257476.webp


Welded and DA sanded

1641616307139.webp


Sanded and blended out the driver side notch also

1641616335181.webp


Fairly minimal intrusion into the frame once it’s all welded back up

1641616372586.webp
 
Planning ahead for the rear sway bar. We are going with a custom length Sway A Way

Bar should sit where the blue sharpie line is and have room to articulate upwards to max bump

Unfortunately about 1/2 of the factory bed mount has to be chopped off since it extends outboard of the frame

1641616437771.webp


See ya!!

1641616481901.webp


I’m officially past the point of fretting about slicing bits off the frame. Just when I think I’m done I end up hacking off more

1641616510571.webp
 
Got all the nonsense holes plugged in on the driver side, used 1” round tube caps

1641616558534.webp


1641616582374.webp


Cleaned off the old mount in preparation for gusseting it again. Using 1/2”-13 welded nutserts

1641616623168.webp


Part of the old mount. The hole is far too large and the bed was obviously loose. All the holes are hogged out

Used an oval tube cap, drilled it to just over 1/2” and welded it in with the correct offset so everything lines up

1641616663657.webp


1641616691627.webp


Gusseted mount, upper mount shortened and welded back in. Uses poly CJ5 body mounts

1641616742898.webp


Last of the old spring hanger bolt holes filled in with silicone bronze

1641616815761.webp
