I run a Delco-Remy (935-C) generator on my '31 "A" roadster. It is off of a '35 Chevy truck and is considered a "heavy-duty" genny with air vents molded in the end plates. The aftermarket mounting bracket is from the later 30's-40's. Delco's produce approximately 5 more amps then stock Ford genny's. The fuse holder next to the Delco-Remy cutout is to protect the system from any shorts in the headlights or horn.
