I bought the replacement pedal for my 1960 from Chevy Duty or American Classic. It's the type that screws to the floor. The attachment fit fine, but within a few months the pedal bent so badly in the middle it started catching on the arm coming out of the firewall. I mean this thing was bent like a bow. I changed to an 60's style aluminum Moon type pedal.
If you want an original style pedal, I'd suggest shopping EBay for an NOS item and pay the price when it becomes available. The aftermarket parts I've purchased including door handles and front fenders have all been very poorly made.
