67 plymouth 383 intake, casting #2205968. Bolts or studs?

[Nelly]

Been pouring though manuals and all information I can find (internet), and I cannot detemine if the intake came stock with studs or if the carb was held down with bolts. Furhtermore, I can not find part numbers for either. Anybody got a solution? I want to run a OEM Carter 4299S AFB on the stock intake. Thanks for your input.

Studs hold the carb down. Get some at auto parts store. 1" long should work. Or 1 1/4 "
