Here's one...just put new u-bolts on the front end of my 74 fj40. Tightened them down and the alignment of the front of the springs (where the bushings fit) are off center with the front end frame mounts (both spring mounts protrude towards the outside of the frame mounts by about 3/4 of an inch). Had to do some serious fandanglin' to get spring mounts into the shackles and now my new aftermarket shackles (these are the cheap shackles like the OEM's from CCOT) are a bit crooked / cocked. This bites...do I need new springs? The pins were centered and inserted on the shackle center mounts when I tightened down the u-bolts, and the frame mounts are straight, front and back. I don't know - maybe this is normal - advise is welcomed!!!
