Curses. Had the fuel gauge in my hand somewhat recently, it's around somewhere, it'll pop up. Really don't feel like digging through boxes today.(It's hot up there ) Was not with my Camaro parts for some reason. Did find a temperature gauge ,large face dated P3 March,1970. 692E-6Q"P3 ? Sort of cool ! Lots of SW gauges floating around here, never paid much mind to them. Would have bet it was an oil pressure. Something to do when the weather turns bad. Any case, you brought up yet another good historic fact John ,something I've never paid much mind to ,but certainly want to finish the car with a cluster of larger diameter temp/oil pressure/fuel. I'm not as gung ho on the "numbers" as I should probably be. I am very intrigued by period correct,properly dated, "upgrades" or "personal" touches.
