You want the open cell ether type foam. Those seals need to breathe. I hope that made sense, it did to my french ears anyways.

So, yeah, off to the tundra, will be wheels up @ 7:45 am.This time, I got a video camera to film some of the tundra from the sky. I will post them when I get time from some work shifts.

Hope the guy's will enjoy.

I would believe that is exactly what GM uses anyway.
I think so to thats what I was going to use. GM has a seal kit 52478817 but it is probably the foam tape you can buy at the hardware store. The pdf says remove the RH and LH instrument panel insulators, not sure what those are?? -28 below!! Its going to be in the 70's here by friday. I think I would freeze up at the temp you have to deal with.

Another question Nick, I've had to backflush the core twice over the years to get the heat working and this is the car we spoke of years ago that overheated in the summer temps. Could a partially blocked heater core cause a restriction to the cooling system? Everything was checked/replaced on that 3.8 including heat gaskets and couldn't find a blockage. I always thought that just maybe the history of the core might be causing the hot engine.

No, a blocked heater core will not cause an engine to overheat there is a bypass for that.
wishfull thinking I quess.. Do you know what a instrument panel insulator is RH and LF are? I'm thinking they are the panels under the dash to firewall??
