Bill, thanks for the reply. Good one on the gun, I guess we're even! The research I've done definately shows US 235's with embossed "Chevrolet" on the valve cover and Canadians plain. Also it seams that the US coils are painted black and the canadian are bright alum. I have seen 3Can. coils this way so far(all reportedly stock). The side view mirror is the 5" round, the one on my truck is deffinatley original with no depressed ring or "ridge" in the mirror's metal backing like the US have. Our milages are rather close, mine has 60,000 documented miles.
Thats all I have found for now.
Greg
