I seem to remember my old 59 Rebel had an access door on the heater box. Four screws and the heater core came out via the engine bay. I know I had one car that did it that way. I'm geetin to think why couldn't you sacrifice a box, cut a door slightly larger than the core, and make an access door. Gonna go check it out.....Russ __________________________________ Yahoo!
