Adding Zerc fittings to poly bushing....
Got the poly bushing from Summit Racing the other day, so now I can install the front sway bar. Ordered just the bushing, not the entire housing. While its apart, I want to add zerk fittings to each bushing assembly so they can be greased. Thinking of drilling a 1/8" hole through the poly bushing. Think its too big? Maybe 3/32?
I know it's not a big deal, just asking.

the small zerk fittings are 1/8 npt, so you need to drill the proper hole, which is not 1/8", for somereason i think its "R" but i have to check. Just make sure the threaded part of the zerk does not come in contact with the sway bar
Checked, it is an "R" bit size

Thanks for the specs, guys. It helps me a lot. I think the zerks I have are 1/8 npt, but will have to double check.

I don't have letter bits, just number. Had to look up the letter sizes to convert to number. But I do have the taps, so it worked out just fine.
