Zerk fittings?

[2slow]

I did a search of the forum and looked through the tech library and couldn't find what I was looking for. Not even sure this is the right section in the forum. But, anyway, I need to replace a missing zerk fitting and I'm not sure if I need metric or SAE. It's for an 87 Ranger 4x4.
Anyone know which I need?
Thanks

Any zerk fitting you will find on a Ranger front suspension are going to be from aftermarket suspension or steering components.

they are most likely 1/4"-28thread, but COULD be the oddball 1/16" pipe thread
(the 1/16" refers to the INSIDE diameter of an obsolete size of pipe)
