I can't tell you anything about model, as it all started with me looking for a heavier chasis for my large frame. Useng sold me a Bronc frame, some shocks, and a rear wheel. I've been gathering parts from hither & yon for two years. Sandblasting is done, ready to primer & paint. I'd like to start assembly. I've got a nice (jeep4me) 7hp Briggs with a 1" 10T (oldsalts) clutch (40-41) for a direct drive. I was going to use a clutch, band brake but I've been looking at a Comet set up at OldMiniBikes. I'll check out jeep2003.
