Alright so I'm new here jus to let you guys know, I have a 86 Chevy short wide with the upper lower sand drop coil springs from djm. Well my problem is that I have a ridiculous amount of shims on the upper control arms that I want gone. I have measured from frame rail to frame rail on the truck to see if I had any issues with the frame in which I compared to another frame and both measured out the same. The truck has had he alignment issue ever since we installed the control arms on it and it bugs the hell out of me. I am hoping someone has had this same issue as me and that we can finally resolve it. I really don't want to get a different set for the truck as i am in the process of becoming an aircraft dispatcher somewhere thank you for your time guys and have a good new year!
