Trans-Dapt Performance Frame Rail Adapter Kits

Trans-Dapt Performance frame rail adapter kits acclimate your non-200R4 frame rail extension car for proper installation of transmission and LS engine. These kits alter the crossmember attachment holes on GM A/G-body cars that do not have a THM200R4 frame rail extension on the driver (left) side, allowing you to fasten Trans-Dapt's crossmember to the frame, and in turn have the capability to install a T56, TH400, 4L60, 65, 70, or 4L80E transmission with an LS engine. These adapter brackets are formed from steel and painted black.
