65 gto backspacing issue-I think

[crustysack]

65 GTO 2" CPP drop spindles Global West tublar control arms, QA1 coil overs and 15" Ralley II wheels with 235/60's- I have been driving it without having it aligned since I finished the build- the car drove straight. I finally bring it to my friends shop for the alignment (on a Hawkeye rack) and he cant align it. He can set the toe, but the camber can not be set properly with out hitting the inside of the fender at the top of the tire. can this be a backspacing issue- or can I correct this problem by changing the backspacing. or maybe there is a different spindle I should have got?? any help is always greatly appreciated
