How is the swap coming along? I too am interested in replacing my SM420 with the NV4500 in my '47 1ton panel. I think the original brake lever was bolted to the side of the transmission. The SM420 came out of a dump truck, and the brake lever is bolted to the side, but it goes to a drum mounted on the rear of the transmission. The crossmember that was behind the transmission is no longer in the truck with no problems for 10 years. I'll want a transfer case on my NV4500, so I don't know if there will be room for a brake lever, I may have to add a foot pedal.
