Installing a Tremec Transmission in your Mustang? 

Then you will need a drive shaft spacer to make up for the difference in length or get a custom-made drive shaft to make up the 3/8-5/8". Our 5/8" Billet Aluminum drive shaft spacer makes up that difference and includes longer hardware for easy installation. Being made from Billet Aluminum means less rotational mass and will keep your drive shaft at the proper length to prevent yoke failure.
