I know this isnt very accurate, but this is what I know. My room mate put a t5 in his truck, and I put one on my car. His was out of an s10 and had to shim it out two washers. Mine was from a v8 capri (yes, according to the code it was a capri. Why the bolt pattern was chevy? I dont know) and it had to be shimmed the same two washers. I have pics on my site about my tranny mount.
