SPC ADJ Control Arms

FYI - I just installed some adj arms on my '69 Barracuda. Everything worked great except the instructions didn't specify whether the bolts on the adjusting rods go in from the top or the bottom. The instructions have a pic showing the bolts going in from the top, which only makes sense if the nut fell off the bolt would tend to stay in the hole as opposed to falling out the bottom. However....now that I've driven the car around for a while I noticed a banging noise when I go over a bump as the front raises up as it usually does. It sounds like something is loose under there. After a close inspection with the flashlight I noticed that the nut on the rear adj arm is hitting the car frame. Of course this only happens when the body rises up far enough to let the front wheel come all the way down. Yes the rubber snubber is there but if the instructions had said to put the bolt in from the bottom it wouldn't have been a problem because the bolt head is much shorter than the lock nut (plus the end of the bolt sticks out a few threads). I've already had the car aligned but it shouldn't be a problem to jack it up and turn the bolt the other way without changing the alignment. Another FYI...the driver's side rear adjusting rod won't adjust enough to get the wheel exactly where it needs. The rear of the wheel need to move toward the frame just a little more to make the alignment perfect but there's no more adjustment. I called SPC and asked if I could remove the rear adjusting rod and take a 1/4" off the end of the threaded rods (they are bottoming out inside the hex sleeve). While I have it disassembled I'll also take 1/8" off each end of the sleeve so I can pull the back of the wheel toward the frame a little more. The tech at SPC said that it shouldn't be a problem because other people have done the same to get a little more adjustment. I finally got the stance I've been wanting....60s street machine!!!
Hope this help someone......
