I think the carb to manifold bolts are 3/8" NC16.
99.9% sure the studs (not bolts) for the air filter to carb are 1/4" NC20.

Carb studs are usually dual thread size. I assume you do mean bolts.

(take half inch spanner sized nuts)

Bolts for carb to manifold are 5/16 unc ( standard forr 99% of us cars) the air filter stud is either 1/4 unc or 5/16 unc unless you have an early dominator ( 5/16 bsw) if you need studs let me know i have some , studs are better than bolts if you intend to keep taking the carb off . i will have some at the nats if you need them.
