40Bud,
The tilton top hung fits fine, altho the pedals are wider spaced than the GTD box. Also the pedals are much longer (hence the better ratio) & need to be mounted correctly. there is room to fit the pedals according to the specs given by Tilton.
I spent alot of time trying different positions for the pedalbox, paying special attention to clearance for your right foot around the steering column (RHD car!)
