I would like to grease my tie rod ends without taking the 15" front wheel off every time. I want to remove my two grease fittings and replace them with 90 degree zerks. What size are they, 6mm metric, 1/8"NPT. 1/4"NPT, or 1/4"-28? A bag of ninety's should yield two that end up pointing the right way, don't you think? Just tell me the size so I don't buy all four!
thanks , edman
