Well, I got one and it sure is a nice kit. Pulled the box last night and realized that a past sin had come back to haunt me.
I've owned her since 1983. In the fall of 85, I started getting the sweet smell and wet floorboards that only a busted heater core can give. I spent an entire Saturday taking it out and installing a new one. Even then the gaskets were already history. So being in college with few $$'s, I got out the trusty silicone and sealed her up, including the seal to the firewall. Fast forward 21 years and you've got a real mess on your hands. 33 year old fiberglass doesn't stand a chance against modern sealant and a strong arm. Now, once I cut everything apart, I've got to reglass the box! FUN, FUN, FUN!!
