I got the trans in and rotating with out any problem!!!!! but now when I install the starter it starts to bind. When I turn the motor over manually or with the starter you hear a thud. I could see some small scaring on the starter. So I took the grinder to that small area but the problem still is there. I have a 67 with a 302 and the trans is from a 71 mustang (C-4). I was wondering is there any difference between a starter from the 71 to the 67? any help or ideas is greatly appreciated.
