Our Customers Speak Highly Of Us.
Jeff J., M.D.
I am totally impressed by the design and machining on these pieces. I was a certified tool-and-die maker for seven years and have three degrees (BS, M. Eng, PhD) in mechanical engineering along with a Professional Engineering license before becoming a medical doctor. It takes A LOT to impress me. Your products are excellent. I have several other old classic cars I want to update to modern transmissions as well

Chris, it was great talking to you the other day when I ordered my kit. I received my adapter kit to install my AOD transmission to my 312 Y blockI I could not be happier with the quality of the components and the speed of shipping. Thank you so much!"

I refer many people to your product as I have personally used the PA kit and experienced several of the PA design faults on my own Bronco. Thanks for your prompt reply. Looking forward to using your kit on my other Bronco.
