anyone have luck installing some 45 degree grease fittings on the rear suspension? 90s wouldn't clear the a arms, I didn't have any 45s around. there is 4 of them. cant get to them with my needle adapter even. changing oils on engine, rear end and front diff is a breeze, they did good there, but access to the grease fittings sucks. the front drive shaft u joint closest to the engine also is not any fun to get to. other than that its a pretty solid design.
