MICHAEL HARTZHEIM
Transmission adapter

Very pleased with the customer service I received when looking a not so common adapter for my 56 olds. They were very knowledgeable about what I was looking for and shipping was right on time. I would definitely recommend them for anyone looking for hard to find adapters. I’m really happy they had what I was looking for.

Thank you for the 5 star revire Michael!
