Tommy,
Thank you for the info. The transmission re-builder knew that the host was going to be a 41 Chevy and the engine was a Chevy 261, so I am hoping that he sent me the right transmission. I think I have the rear-end problem solved and have two choices in my shop. One is out of a 56 Chevy PU and other one out of a 70 Chevelle with all of the extra clips removed. There is a drive shaft builder not far from my shop that will make one to fit when all else is installed. The problem I am still stuck on is what bellhousing will bolt up to the 261 and to the Chevy T-5.
