Thanks, I don't care what I have to do to make it work as long as it will work properly and safe. I am a machinist so anything in that area doesn't bother me at all. I would love any help you would be able to give me! I read in a book about machining off the extension, but I can't find out how much? I have the original setup so getting the length from trans to bellhousing surface at block shouldn't be difficult. Like you said Mike P, maybe I don't need to take as much off the block so I don't need an adapter.
