By any chance does anyone know how hard it is to change out a heater core on a 93 chevy cheyenne, 1/2 ton, 4.3 with a/c?

Man I haven't done that exact year but it isn't too hard to change just takes a while to get to it.

Thanks oilpatchpride, I already have it changed out. Not bad at all but like you said just a little fiddeling to getto.About 6 screws to take off a small bottom portion of the duct work and there it is.
