I spend a few hours today to tackle a check-list item. I made a pedal box that will give me about 2.5" of extra leg room. It’s 10"W x 12"T x 2.5"D. The mounting flange mimics the flange mounting the heater box on the firewall, so it’ll look OEM once installed. I don’t have a spot welder, I drilled and filled with my Tig from the inside.
I’ve got a set of “Trick” pedals from Bassett. Smaller foot pad, shorter shaft.
