Hello! I'm in need of some serious advice regarding my 52 GMC suburban. It is stone stock with a 248 and only 80000 origional miles. I also have a 68 chevy van 109 wb heavy duty with finned brake drums , 6 lug wheels, 12 bolt rear and factory 4 speed col shifted borg warner t 10. Thinking of swapping rear and tranny converting obviously to open drive. Does any one know if the t10 is a bolt in? Any advice would be greatly appreciated! I also am wondering if I could swap the front brakes to the finned ones from the van. Thanks, Smitty
