Marc..that is a coincidence! Bill grew up the next street over from me,in Warren! We use to do a little "street racing" together..back in the early-late 70's! Like I stated,Bill puts rears together to last! In fact,he told me,with the way I drove the X...my 4:56 wouldn't last but 1 or 2 times to the track! Still proving him wrong! His assumption was based on the pinion design,and old-style case! I make a point to tell him the rear end's STILL in one piece,every time I see,or talk to him! Ryan..call him,you won't be sorry!
