The last 48 hours have been busy ones. I've ordered some parts for a stereo installation, including sound deadening materials, so I decided to strip out the interior (again). I'm also going to be installing a few more 94-96 interior bits as I finish up. Because I wanted to remove all of the original flimsy padding/deadening, I had to remove a significant portion of the dash - at which point I decided to "go for broke" and remove enough to get to the heater core, which is original. No signs of leaks, but Murphy's law would indicate that a leak would appear at the worst possible moment.
So, I pulled the heater core, and sure enough, it was seeping from a few places, obviously corroded especially at the bottom. Guess it was on borrowed time!
I'm also installing the tccrabs starter relay, and a Harlan shift light, while everything is apart. I've got some pics to follow, plus some pics to go along with tccrabs excellent threads on the "Dreaded No Start".
