Just curious, but what type of tranny are you putting in and why? I thought you were an OEM man. By the way, I have a whole bunch of spacers that you can have. I was told, by installation instructions, that I might need a spacer and that they came in a pack of five for you to select the right one. (Unfortunately, you have to assemble and test for play to get it right) When I ordered, a pack of 12 came, and they all seem to be the same size(thickness). I know that I wont need all of them so I can send you some. Bill Spruill, oldest Colt
