ok got 16 zerk fitting for my labreck bushings...noticed they are npt threads...what size should the zerk fittings be...all of mine are the same size...i'd say about od = 1/8"

So which tap to get? Are these fitting sizes ok for rear diff bushings?

thanks

damn everytime I think my car will be ready...now changing bushings is going to be pita!

What thread size does the package say? If it is 1/8 NPT, you need a 1/8 NPT tap. The package for the tap may list the drill size you need, or you can probably look it up somewhere.
