So I ended up buying just 2 of the 90 degree fittings for the rear knuckles and that worked fine (local hardware store had them, go figure). And there was no f'n way I was going to be able to hit the stock ones without taking the wheel off. I also noted on the front a-arms they had 45 degree fittings which made no sense since you could easily get to them with just a regular grease fitting, so I put the ones from the rear knuckles on the front a-arms. The chinese....I swear.
