Update-Chicago area alignment shop
I stopped in the Firestone by my house today to ask them if they would be able to do the alignment on my 78. The guy said "let me go check the machine, I'm not sure if it goes back that far". He came back and said "yes the machine says we can do it". So I asked him if he had experience with the shims and that I would give him SS shims to use. He said "we only have one size shim and we can't use yours because it would not be under warranty". $129.00 I said OK I'll think about it and ran out the door.
I then called 59 Auto in Plainfield IL and talked to one of the owners and he knew from the get go how to align the C3 and how to shim. $60 for front $89 for 4 wheel. He said he would check the 4 wheel and let me know if he needed to touch the rear.
Has anyone ever gone to 59 Auto in Plainfield? They seem like they know what they're talking about.
