Supercarbob,
Thanks for the info

Clearing the cobwebs a little, seem to remember parting a '70 LeMans Sport with a 400 2bbl back in the early 90's. Makes sense that it was avail in a GT-37 as well.
On the '70 1/2 Orbit Orange GT-37, do you remember what color the stripes were? Was the dealership in IL? THANKS.
