The heater core is simple, once you have the dash out. I need to do it again. Uggh. This time, though, the the entire dash assembly has turned into shards and powder.
I was able to locate a decent used dash (minus the top) from a 1994 that had been transplanted into a 1997 at a wrecking yard. The color matched, but I am planning to repaint it anyway as kind of a sealer. I juse need to decide if I am going to do the dash transplant before or after the truck repaint. Probably before, so I run less downside from scratching up the paint. If I scratch up what's left of the paint, no worries.
