This screw / stud seems to always be missing. This screw is just a little longer than stock to accommodate installing the Hi-Po air cleaner. Fits most Autolite carburetors. Size: 4 1/8 inches length 1/4-20 X 5/16-18 threads. Check your thread size on the carburetor, we think that starting in 1969 the Autolite 4300 carburetors had 1/4-20 threads. Please note that this stud has 5/16-18 threads going into the carburetor.
Replaces Ford Part #: 370971-A
*Note - Check your carburetor, it will need to accept 5/16-18 threads. There are several versions of the carburetor housing. It is not uncommon for rebuilders to switch bases and main housings, there are also Autolite and Motorcraft carburetors with 1/4-20 threads for the air cleaner bolt.
