I was doing a 4 wheel alignment on a 32 ford truck today at work,I was adjusting the rear 4 bar and thought something didnt look right on the rear end. I finally realised that the backing plates were upside down!! I mean the wheel cylinders were on the bottom and the e-brake cables on top! It is a currie 9 inch,and the owner said he bought the rear end fully assembled from currie. Is this something new that I havent heard about or could it be a major mistake? I am sure they could be switched from side to side and turned over if necessary.
