Thanks. Overall Im very happy with the cuts. In the rear I folded the lip straight made some cuts to allow the fold then folded in into the wheelwell and welded together. On the front, I Welded in 1/4" round stock along the entire cut, it makes for a really solid fender.
On the hydro, yeah, Ill be tapping to oem 80 box that I have.

:cheers:
 
Well things are moving very slowly. But I am close.
Ive got my rear air bumps in place, did some limit straps, got the fuel lines mostly finished, body work is coming along but still have a bit to go.
Ill let the pictures do most of the talking. Enjoy........

80 axles are about 5" wider.


I'm about to start compiling parts for my fj80 rear swap, and I'm still not sure weather to do the standard 5 link, or triangulate the uppers and ditch the panhard. After going with the triangulated 4 link, do you think it's the best way to go?

Yeah, for me, the 4link was a better option. The rear of the 60 has ample room for triangulated uppers. I liked that I could weld new mounts for the uppers right to the inside of the frame rather than having to make a cross-member if I went with the stock 80 setup. Either way I think you will be happy.

It does seem to simplify the setup for sure. What angle were you able to make your uppers? Also what did you do with all the hard lines on he inside of the frame rail on the passenger side with the link bracket there?

Ill try and remember to get a picture of it tomorrow but I simply put a few bends in them to go up and over my mount. My uppers are angled at 22.5 degrees.
So they make a 45 degree angle from the axle.

Once I get the truck on the road Ill play around with sway bars. I have the oem 80 bars on now. I think its always a good idea to run a sway bar, never know when you'll need to do a quick swerve. I think Ill end up with some antirock style bars.

HOLY :censor:! I haven't ventured into this thread for a while. Looking damn good man! I love the blacked out 80 wheels, though I don't know if the tires you picked will have good road manners:p

When's the maiden voyage expected?

Haha, we'll see about the tires. The price was just too good to pass. Im hoping to have it driving within the next few weeks. :cheers:
 
bumps

I think the air bumps are suposed to give you a more progressive stop so a kind of emergency shoch absorber.Instead of the axel hitting a solid lump of rubber it comes to a softer stop.On the IH8MUD home page there is an article about parabolic leaf springs on their site there is some pics and info on all bumps .Hope this helps.

P.S thank you for the hj porn ,coil springs are one of my fantasys!:o
 
It lives! First test drive was last night. Ended up having to tow it home lol. The alternator wasn't charging. Well I got that figured out and went for a short drive today. Its not yet registered so I didn't go far but I can already tell that the ride is going to be very nice. Everything feels tight and I really like that the 80 steering box is a lot quicker. Also, I cannot even feel the tires, they are quite and drive very smooth, we'll see how I feel once I get it up to highway speed. Ill get it out more as soon as my reg. stickers arrives. Im really looking forward to getting dirty. Heres a few pictures of it in the driveway.
