Spent some time working on this again today, got the Sawzall, torch and grinder out and cut the rear coil buckets and lower link mounts off the rear axle.... then used the wire wheel to clean up the axle best I could. Next, I welded up my rear 4 Link Brackets and tacked them into place... then built my rear-upper links. I ordered some new, lower link brackets and am waiting on them to show up, then can cut the lowers into place. I got all my parts from RuffStuff and they're serious BEEF. Probably a bit too big for this little Willys, but they'll last a long time and be damn near bulletproof.
The rear links are shorter than I wanted, but I'm limited by the wheelbase and t-case. The front lower links will be longer than the rears by a few inches, not a big deal but I'd like longer rather than shorter.
As expected, my front driveshaft with the 4L60E/Dana 300 combo is going to be TIGHT. I believe I can build a driveshaft like a CJ front, with 1 1/4" x .120" tube and make it work. I'd rather not run a pillow block and 2 piece driveshaft, so I'll see if I can make it work.
This pic is 1" tube sitting in the center of the yoke on the t-case and front axle....
