need to fix my heat before winter!

[90windsor]

all last winter my heat barely blew at all, until i realized there was a giant melted hole in the black plastic that surrounds the heater core and a/c stuff. obviously from the manifolds a long time ago. i just patched it with some duct tape and a towel, but i want to fix it right. i cant seem to find the heater box. looked JBG and ebay. nothing. anyone know where i can find one? or some of that aluminum stuff with insulation on the inside that most cars use on the firewall? ive looked everywhere for that (the previous owner patched it with that)

I'd get the box (called heater plenum in some references) from a yard; esp since the yards around this area have many Broncos & F Series with no engines (they take em out along w/tranny/Xfer case right away) so it is ez to remove

I like the 3M Aluminum Foil Insulation Tape
