Easy installation. Great item

Worked great on my 1963 Cadillac. Was able to mate the original Cadillac 390 to a chevy 700R4 .

We are happy to hear :)

This kit fit perfectly. All I had to is cut the pins a little shorter on the block. After that everything bolted on in minutes. I would recommend this kit to everyone that wants to upgrade their transmission in their classic car.

Thank you Jason, we are happy you had a great experience with our CA101 kit.
