Great parts fit perfect

I have two cars currently using this speedgems adapter kit. It works as designed, I’m happy with the quality. The car shifts through gears like it came this way from the factory.

2nd time that I have purchased a kit from them. Great product, fast shipping, great people!

It worked great they installment went real easy no problems. All I had to do was shorten my driveshaft and change my linkage up a little bit, but it’s great thank you.
