small block 340 driveline in a big block 727

Yes, we are talking about 727 SB and bb. I must just be not getting the splines lined up. I'll have to try again tomorrow morning when I'm not dragging my tail tired.
We have been working nonstop on it. Thanks for verifying what I was thinking was the problem. I'm glad you guys at Fabo are here to bounce problems and ideas off of to help get this done!
