The Zerks - otherwise the giggling will start again :-) - should be 1/8th BSP - I say should be because my owned-from-new +8 has 1/8th BSP on the nearside and something that is not 1/8th BSP on the offside.
I am toying with the idea of fitting a remote greaser because accessing the nipples zerks with AVOs is a bit of a pain but would grovel on the floor afterwards to clean up and check fittings
