I know there's a thread somewhere on here . I just didn't look for it . I just acquired a Ford 9" with 3:70 gears . I measured the backing plates to find that they were like 2 3/4 inches shorter than the 8.5 that's in my '80 Mirada . I'm still gonna use it . Can't beat what I got . So ,,,,,,, ! Here's the question ! What material thickness did y'all use to move them inboard ? Pics would be good too !
