AMK part number B-11693. Correct head, threaded and secured with a nut. I have many people that would press a correct rivet if requested. I suppose if one is dumping bags full of money into a car for judging purposes this very important. I'll be buying my friend's original rot free, 70 % original paint Cobra Jet four speed 1970 Torino for $16K. Nice driver and I will leave it out in the rain if I have to. Crazy how people spend over $100K or more to restore a car worth $50K.
