What size threaded rod for carb mounting studs?
I am changing the Holley on my '72 GTO back to an original QJet. One problem, I can't find mounting studs anywhere. I plan on getting some threaded rod and cutting off what I need. I just need to know what size threads are used for the studs. Does anyone know? Thanks!

Most carb studs are made with 5/16-18 coarse thread on the bottom to thread into the intake, and 5/16-24 fine thread on the top to attach the carb.
Buy some 5/16-18 coarse thread rod to make your own studs.

you probably already know this, but if you put a nut on the rod before cutting it and then unscrew the nut after the cut it will help keep your threads in usable shape and prevent cross threading.
