I have a MK4 with a foxbody 8.8 rear end and a Mustang aftermarket 4-link using the Mustang springs.The body is on straight but the rear wheels are too far back in the wheel wells. There are no adjustments in the control arms or other holes in the chassis to bolt too. Has anybody else have this problem? Thanks

Have you done a front wheel alignment and are they centred in the wheel wells. The body does have to be aligned properly fore and aft with reference to the door latch striker post being the critical point. Jeff Kleiner has some real good posts on doing this. I have exactly the same setup and here is a picture of mine. I think it is lined up pretty well. There are aftermarket adjustable upper and lower control arms available but I would go three link with coil overs before spending on those.

My rear wheels are centered; however, I had to shorten the wheelbase to pull it off.

Taking this action is more involved than you may think, especially because of the driveshaft yoke depth.

Hope This Helps & Yes Mar Has Been Properly Aligned!

Unfortunately there isn't much you can do unless you replace the links. This has been kind of a problem w/ MkIV bodies until the recent redo.
One possible solution: https://www.breezeautomotive.com/shop/rod-end-rear-lower-control-arm-kit/
Or, if you really want something specific, any 4x4 shop can fabricate a set of adjustable link end bars for you to your specification.

Thank You to everybody for the replys. I am going to order adjustable rear end links. I think I am going to go ahead an convert to rear coilovers as well. Anybody got a set of rear coilovers they want to sell???

I had the same issues as well when I set up my car. I have coilovers, 4 link and adjustable UPPER control arms (by Spohn). I believe Mark doesn't recommend the adjustable lower control arms on a 4 link as they have no real way of centering the rear end. Best to check with him before ordering. I did find that I was able to get considerable adjustment just by adjusting the adjustable upper links. Almost perfectly centered in the wheel well. I will have to re-adjust my pinion angle but will try to do this by raising/lowering the transmission tailshaft with spacers.
Also make sure you follow J Kleiner's tips on mounting the body....Door latch mount should be approx. 1/8th to 3/16th behind the door opening lip. You may have to remove material from your front and rear cockpit lips to obtain this (I ended up removing and reinstalling the body several times to accommodate this).
One more thing...you will need to have a proper wheel alignment of the front end so you have a reference point for your axle to axle distance....
Good luck.
