Check ball retainer screw thread size
« on: January 07, 2021, 02:09:50 PM »
I picked up a basket case 73 Pontiac qjet with a leaded over plug on the stripped threads check ball retainer screw?...anyone know the stock thread size of the retainer screw?. I'm hoping to find a oversize insert to salvage this build. Thanks.

Going from memory I think they are 1/4" fine threads but I'd have to go check one to make sure....
