Need Accurate Measurement From A CJ...

I need to know the distance from bolt center to bolt center on '76 or newer CJ leaf springs, both front & back.

I don't have an unmodified jeep around here, so if Jim Lou, LEVE or some of the more trusted guys wouldn't mind throwing a tape at their spring eye bolts, I'd sure appreciate it!

Here are the frame dimensions from the '78 fsm. The actual spring dimension depends on the weight on the spring, unless you're looking for the length of the main leaf. I can get that too if that's what you need.

As best as I can measure, trying to follow the arch of the spring, the front main leaf on my 7 is 44 3/4", and the rear is 45 1/2".

Nope, just need the distance from frame mount bolt hole to frame mount bolt hole.
I'm putting a set of frame mounts on a new frame and don't have a stock set to measure from around here.

Looks like 40.61" in the front, and 46.16" in the rear....
Sound right to you guys?

I'm just trying to find the stock locations...
Nothing I have is stock anymore!

Anyway, I'm not sure I have your phone number, send it to me on a PM...
Computer crash a month ago took everything I didn't have backed up, and additions to my phone lists was one of the things that went.
(I still hate XP!)

Not accurate or anything close by myself.

But on mine.......on the jeep....on the ground(not that it matters on the frame)

Eye to eye on the spring mount "spring bolts"


front 44 3/4"

Rear 44 1/4"

That is "close". I hooked the tape over the head of the one bolt, measured to center and guestimated what to take off for center of the first. Wife went to bed so I didn't have the extra set of hands.

Like I said, call me if you need more info.

I'm looking for the frame mount to frame mount center,
not the spring eye centers.

I'm going to make a jig with the frame mounts at the correct distance apart, and have it hold the mounts the correct distance apart and parallel with each other and the frame while I weld them in.

I need to know how far apart they need to be on the frame.
