I had the same idea for the dash cluster. MAy as well...like you said, it goes with what's under the hood anyway. My gas tank is a mystery in that it was replaced by the original owner in '74 with this HUGE 37 gal tank made of 3/16 inch steel. (heavy). Eventually I'll rebuild another like it with the in-tank pump. ( I can't stand the noise. It's embarrassing at a stop light)
one question...how long did it take you to write that first (awesome) post???? ( which is why I sent you a LINK instead...)MArty
