Thanks to everyone for the advice on the installation of the engine and transmission in my 64 roadster. I finally got them mated back together this afternoon after a little bit of wiggling and some raising and lowering of the engine while pushing the trans in. Apparently the two components were just not lined up correctly and with a little patience and some dumb luck, it all went together. The support brackets and shifter went back in with no problem and once I get it wired back up I'll be making noise in no time. Thanks again to everyone for offering up your expertise and experiences, it made the job a lot easier.
