Heater Box Help.

[quick60]

I took my heater box off the firewall today and have several concerns/questions.

1. The area on the inside (see pic) is badly rusted along the bottom. Very thin sheet metal to begin with. Are there any repair or aftermarket replacement parts for this. I looked at LMC and found nothing.

2. There was a thick layer of some type of black gooey caulk that sealed the box to the firewall. When I replace this what should I use to reseal it?

3. The interior heater box duct was rusted as well. Any aftermarket replacements for this box as well?

4. Is the rubber boot around the fan duct inlet available anywhere?

Thanks!!!!

there should be a lot of heater boxes in the pick and pulls , or some one here should have some for sale. you should be able to use any good sealer to put it all back in when you are ready...good luck on your project..

I used 3M round ribbon window sealer in the channel around the box. Worked like a charm. A big roll of it was under 20 bucks.

LMC has the blower motor gasket for 15.00 They also have a full gasket kit with the sealer. At the bottom of page, No. 8

I'm using 3M strip-calk. Its actually the same thing GM used to seal the boxes back in the day.
