Hi,
Thanks Rob, Lynn and George for the encouragement! I need all I can get.
George, thanks for the offer about the information on the C8 owner you know about. Would like to see what he has.... And yes, we have had some very odd weather here in Texas this winter, with record low temperatures and snowfalls for the area.
Installed all the adapters and all but one of the C8 wheels today, and in spite of all the modifications I did, things went fairly smooth,(note that the cooling fins on the new brake drums are now removed, as they interfered with the 13" rims).
Added the longer wheel studs all around to accomodate the thicker mounting surfaces on the aluminum adapters.
Wheels and tires went on next, and I think it all doesn't look too shabby considering.....
I am glad to have this phase of the project behind me!

Thanks, David
