Gmc grease fittings
Have a 2011 GMC 3500 Duramax. Two of the grease fittings are hard to get to, would like to change to 90 degree fittings. Does anyone know the tread size of the fittings.

I have a 2012 and yes the inner three grease fitting are a bit tough to get to. I first picked up a set of the 90* zerks but found them to be a pain to point in the direction I wanted and also be snug. You have to shim them with small washers to get them to line up the way you want. I ditched them and picked up a 90* adapter for the grease gun. Problem solved and much simpler.
