I'm in the process of fitting some 19 x 11 rear rims on my truck and the stock 8 1/4" rear width looks to be perfect. I have heard that an 8 3/4 from a C-body is the same width and only the spring perches will need to be moved. Does anyone mind sharing the ins/outs of this swap ? Also what year of C-body am I looking for? Its tough to find specs on these trucks such as 8 1/4 rear widths/specs. Thanks in advance. J.Rob
