Were connections between the hot-air metal ducts linking the H/E and the body originally supplied with gaskets?

If so, is there a source? If no source what's a good substitute?

While I'm asking, has anyone used foil tape or another material to seal the many seams of the hot-air system?

The only gaskets used that I know of were the ones at the HE to fan connection. Last time I bought them from AA for way too much but I used em as a template. Does make a difference to seal that connection. The rest should be just factory setup.
The little aluminum deflectors are nice to have too.

I have a the ones in the engine tin as well as high temp silicone hose as well as a lower temp version that can be used on the other ducting

Much obliged. You are on my list for HT silicon hot air hose as soon as I gather some some more aluminum cans. I found one of the "grommets" and am looking for the other one. Thanks.

?

"foil" duct tape should work fine (till ya go to take it off).

Yup, foil tape is sticky stuff -- thanks for your input Curtis.

I have 'em. What are they for?
