Does anyone have the 2 Thermostat housing bolts for a 1991 Trans Am 305 TPi if that makes a difference . Ive had slight leaking issues with the bolts that were put in from the previous owner and I can't seem to find replacements.. Ive gone to the Chevy to try and purchase replacements and they say they are no longer available. I would like to keep it factory without using aftermarket Bolts.. ANYONE have a spare set sitting around they could sell me?

thanks Ray
