Hope you have alot of this $$$$$ and Time

without sarcasm please help me out as this is my 1st build with an FJ.
I do lots of fabrication so all the custom work is no problem. Just need to start collecting parts in order of importance ect.

Looking at brakes. I'm leaning towards the man a fre 6 piston Willwoods in front. There rotors in rear with 4 piston Willwood calipers and custom brackets.

I need to figure out the axle set up 1st so I can start on that. I like the fj60 idea to widen the stance and I can rebuild on the side so as not to take apart the running FJ and have it sit

With the added width of the 60 axle, leafs springs will need to be out boarded to clear the diff housing. You get the stronger steering arm studs and decent disc brakes.

I'm upgrading the disk brakes regardless.
I'm not sure what way to go on the axles. Maybe later model 40s and do the upgrades or many mini truck. What's my best option here?

Have you picked up your 1968 FJ40 yet?

If you are planning on that many upgrades why limit yourself?

Toyota 9.5" Land Cruiser Axle Housing

 

[Shag55]

Yes. Its all original now

 

[thebigredrocker]

Sounds like a cool project

I thought I'd throw a few ideas out for brainstorming.

On my build for the front axle I'm using a 74' front housing and one of @lcwizard 2-5/8" extension sleeves on the short side and cut & turn. Getting a set of FJ60 Knuckle balls as the ones from my housing are a bit pitted, so that gives me knuckles that don't need grinding and a WMS to WMS of 60".

Rebuilding an FJ80 steering box with OEM rebuild kit, 105 sector shaft & pitman arm from Beno. The FJ80 steering box has the same mounting bolt pattern as the later FJ60 & 62, but is stronger and more powerful than the FJ60, probably not really needed though.

The FJ80 steering boxes seem to twist sector shafts, I'm guessing because being more powerful than the FJ60 boxes which don't seem to have the issue. But the 105 Sector shaft & pitman arm eliminates the issue, makes it bullet proof.

Using Sixshooter knuckles, all ARP studs, 4x4 Labs steering arms & steer from behind crossover, vented FJ60 discs, mini truck V6 calipers (4 43mm pistons vs FJ60 2 43mm & 2 33.8mm pistons) and RCV cromo shafts, birfs, 4340 hub gears, 4Plus SR, Mohave springs, u-bolt flip kit & new design shock towers, Ruff Stuff diff housing welded on, RS spring under (they have them for spring over and spring under) spring perches, spring hangers, steering stops & Marlin HD Knuckle Gusset Kit . FJ60 vented rotors and calipers on rear since the less powerful FJ60 calipers will be easier balance with proportioning valve.

Have an 87' FJ60 TC to rebuild and put AA 4.1 gears in, TSM's newer disc parking brake, B1000 Lay down ratchet style parking brake lever, it's longer and has more leverage Emergency Brake Lever B1000 - Lay Down Ratchet Style (PN#B1000)

Cheers, Allen

On the fj60 Box I'm going to order the pitman arm. Should I go with the drop one from trail gear or the straight?
This is SUA set up

 

[abosely]

Are you having Luke at 4x4 Labs build your steering system?

If you are I'd call Luke & ask.

[Shag55]

No. Just collecting the parts to do it.

 

[Mace]

Sooooo, links or leaves?

 

[Shag55]

Leaves

Spring under axle you are looking at about a 4" lift to fit 35's without a lot of cutting. I'd go later model 40 series axles. minitruck won't have the correct offset.

I believe that 68 should have had the birfield design instead of the ball and claw. so you could keep your existing axles and just upgrade the knuckles.

I'd use later 40/60 stuff for the Vented rotors and but aftermarket Birfs if you are planning to run lockers.

Split tcases are tough, but you would need to address the parking brake issue.

 

[Shag55]

I'm going with the TSM parking brake
Now I just need to find a set of 78 or later model axles local here in so cal.
I think I'll go with the Longfields.

 

[Shag55]

Late model 40 knuckles or fj60 ones?
