Waiting on grips in the mail, have to cut down jack shift brake cable, install clutch brake handle/cable and I’ll be finished up. Gonna take it to autorama the first weekend in March.

Outstanding work here.
I am fully unfamiliar with powder coating metals that get hot and how the coating performs. I've got some reading to do. We just completed a big sheet metal body powder coat project and I never thought of the engine or exhaust system.
Nice fender paint work.
