the hole at the back of the valley in the block. Does that need to be plugged? there was some ****ty plastic thing in there that broke when i touched it with a shop vac.
if so what is the part number for that plug anybody?
I begin reassembly tonight and would love to know before i get to the point where it is holding me up...which in all likelihood won't be until thursday.
