heater/ac door rubbers

I'm trying to restore my heater box. A critter has made a condo out of the inside and it chewed up all the rubber off the interior door flaps. I went to several salvage yards and the critter must of had relatives moved in every truck I checked out. They also were chewed up. Does any body know if there is a company who sells replacement doors for these boxes?

They make replacements for every piece but not just the rubber flapper's. You will have to buy the whole part.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Remove the "flapper" go to home depot and buy a small sheet of neoprene rubber cut to fit and install using long pop rivets with washers .

Re: heater/ac door rubbers

Yeah, I thought of that. But my problem is I don't know exactly what they are supposed to look like or size. These boxes if in good shape can be a pain to operate correctly. If the seal is to big, the slide control wont work right or the knob breaks off. If the rubber is to small, it leaks like mine does now. The air travels around the door because there isn't any rubber to seal it properly. What ever made a nest in there (my guess a mouse) chewed the rubber off all around the doors to the metal. The door where the heater core is looks to be a weird shape.

Re: heater/ac door rubbers

I used truck tire inner tube to repair mine. Got the inner tube for free at the local tire shop. My originals were completely gone so I over sized them a bit and then trimmed them to fit. As said above I used longer pop rivets with washers on the back of the rivets.
