I just got back into town so it will be a day or so before I can get some pics.
FYI...I used stock TJ Wrangler springs front and rear...both 2" wide. On the front, the wrangler spring is about 1" longer than the CJ spring. I used aftermarket rear spring hangers on the front. I drilled out the rivet and moved the hanger forward an inch and ran a grade 8 bolt through the hole where the rivet used to be. It sits perfect.
The only 'dificult' part is the spring perches. Buy new ones....don't make the mistake I made of using stock ones. You can buy longer ones that will help reduce the spring wrap. On the rear, mount everything up and adjust your axle for proper drive angle...and then weld the perches. If you don't have a CV drive shat...stop...don't even think of doing the SOA with out it. You will never be able to shim the axle correctly to get out all the vibration. By using the CV driveshaft you then just point the pumpkin right at the xfer case.
On the front, I did the same basic operation...but before welding the perches, I took (towed) it to the alignement shop to get it aligned properly.
You will need to weld on shock mounts. Don't do like some guys and use your original shock mounting plate on top....it looks like
and reduces your potential axle travel. Plan on needing new shocks (measure before you buy).
As for spring plates to the U-bolts....the rear spring plate from an Chrokee fits perfect. In most cases, you can just walk through the junk yard, look under any Cherokee that has had the rear axle pulled off and find the plates laying on the groung.
Since your in LA, one of the best sources for used jeep parts is AMC Auto Salvage in Wilmington (323) 775-2823...They are located on Lomita BL where it ends right after Wilmington AV.
Looks like we are both in the same area (I'm basically in N Torrance). Yell if you want to come by and look at it. Wife just had another baby so I try to stay at home as much as possible...I got some boys to teach about jeeps....
