Grease fittings

[markqc]

Anyone know the thread size of the grease fittings for the upper ball joints? Vehicle is 1996 C1500 2WD 4.3L. The originals need to be replaced but I would rather have them on hand when changing them out.

Thanks,

Mark

There is two sises. Small and large. But they only use small any more.
Your local parts place should have some .
But to be on the safe side screw a old one out and take it with you.
