For Tremec Magnum 6-speed transmission conversions.

This laser-cut Hurst tunnel patch kit is designed for 1978-1988 GM G-Body applications when doing a Tremec Magnum 6-speed transmission conversion. The 2-piece tunnel patch is constructed from 18-gauge mild steel and comes with a pre-cut hole for the correct shifter stick location, along with pre-drilled holes that can be used for locating holes and/or welding to your existing floor pan. Includes a CAD drawn template with the correct layout for trimming the factory floor hump to properly accommodate the Tremec Magnum transmission.
