Been researchin' this and Scott, yur right on as usual. McMaster has the hose and adaptors listed on their current catalog, page 199(winter 2007). They also have the 3" aluminum exhaust ports for $33 just like the ones I used to have at the old house.
I stopped at a garaged door shop and they wanted half a hundred and Mainards priced them at $45.
So I got another order into McMaster this week. Thanks for all the input.

Yep Josiah, I'd have to agree with that statement. We've/I've ran cars inside garages all the time in the winter but always used the proper size and material for ducting and made sure that there were no exhaust leaks. It scares me when I hear about using drier vent hose and some of the other stuff suggested that are not approved for venting exhaust fumes. That's just an accident waiting to happen in my opinion. It's a hundred buck investment that will last your lifetime. I've had a set of hoses for many decades now and they are still in good shape.
