5" shackles on front and rear of CJ7 - Adjustable?

I have recently purchased an 81 CJ7. As I'm going through it, and learning some of the ins and outs of the Jeep, I've realized that the PO put aftermarket shackles on. My understanding is that the standard "hole-to-hole" shackle is 3", and these are 5", which I believe equates to about a 1" overall lift. I've also learned that any lift at the shackles may affect steering feel. Since I'm getting a little bit of drift and the steering doesn't seem to want to center after a corner, I'd like to get this back to standard and see if that helps.

My question is... these shackles have a middle hole at about 3.5" that is not being used. Is is possible that I could just move the connecting point to this hole and be back to Stock? Or is this middle supposed to be a reinforcement point for the shackle that the PO did not install correctly?

Second question... Since I'll lose about an inch of lift, do you think (from the pictures) that I'll end up with a problem with the tires? It would seem that I could absorb an inch of lost lift pretty easily... but not sure what the cascading impact might be.

(Finally, I'm replacing/reinforcing the rear frame next week, prior to replacing the shackles as I am aware it is very rusty)

Thanks for the advice... Turns out that there is more work to do then I first expected... but I guess that will be part of the fun!

Do those shackles have any kind of crossbar connecting the two sides welded in? I think I see one in the second to last picture.

If not, the empty bolt hole was probably supposed to be a connecting bolt. If there is a crossbar, by all means, use that hole.

Agreed. Any shackle that long should have a support block between. However, your steering issue may not be due to those shackles. That's not a given. You really need to find out what your caster is to know. Caster has some wiggle room and yours is probably to be set between 5 and 7, but 4 may not effect the steering that bad. I've had 5 3/8" shackles on for years without steering problems on the stock springs. Adding caster shims would be your easiest fix once you find out what your caster is, if it is out too far.

Shackles that long have a tendency to "rack" which may affect steering/handling also.

I have seen those type of shackles used in the stock height holes several times with the tails hanging down. I would move them up.
