Grease fitting thread size for countershaft Z bar
What size grease fitting does the 1967 GTO 4 speed countershaft use? The hole is definitely 3/8" diameter but not sure which thread size to use. Is it tapered or straight? Any help is appreciated.

Talking about the Z-bar? I only have the one in my car and memory isn't good enough to remember when I welded up the original and made another to clear the Doug's header tube. If it looks like 3/8" diameter then it is a 1/8" NPT thread. If out of the car, a 1/8" pipe nipple should screw into the hole.

Got a 1/8"-27 NPT grease fitting today and it fits perfectly. Thanks Mick!
