This custom laser-cut tunnel patch is designed for installing a Tremec TKO 5-speed manual transmission into 1968-1972 GM A-Bodies and is compatible with a bench seat, bucket seats and with or without a factory center console. It is specifically fitted for automatic floor pan vehicles, but can also be used on factory manual shift vehicles by further trimming the floor pan around the factory hump. Includes a pre-cut shifter hole in the proper location for the TKO transmission, is made from 18-gauge cold rolled steel and comes in a raw finish for ease of welding. This tunnel patch was designed to be used with Hurst part# 67510020 adjustable cross-member (available separately) that fits most all GM A-body coupes and convertibles with a Tremec TKO, Tremec Magnum 6-speed, GM TH350, TH400, 700R4 and many GM manual transmissions.
