Gearbox is situated between frame horns to begin marking area to be cut for the inner shift-rod that will enter tunnel in the new location
Slide 56- Type I IRS Chassis Prep
Using a wire wheel, area to be cut was cleaned to enable marking of the necessary patter for the shifter coupling to fit through the tunnel:
Porsche Shifter Coupling requires hole cut to 60mm x 120m
If using a VW Shifter Coupling it requires hole cut to 70mm x 120mm, due to larger size
