For over 25 years, CPC has earned its reputation as the leader in T-5 Conversion kits; featuring the signature adapter plate. Our T 5 adapter plate is designed to install a late model Tremec 5 Speed Transmission onto your early model Mustang.

This adapter plate installs between the T-5 transmission and the early model transmission bell housing for easy installation. This adapter requires 2 holes to be drilled into the bell housing; casting # C3AA-6394-C

Includes:

  • (1) Adapter plate
  • (1) Hardware kit

CPC Recommends using a 1985-1993 T-5 or an 1985-1993 World Class Borg Warner T5 Transmission. (1994-up input shafts are too long and will not work with our conversions)

Proudly manufactured by CPC in the USA with limited lifetime warranty
