Roller lifters A engine

I am in the process of installing the tube kit in my 69-340 block.I have reamed the right side oil gallery,and am preparing to install the tubes.It seems that I have misplaced the long drill bit that came in the kit.Does anyone know the size of the drill bit used to drill the main bearing oil passages ,and up through the tubes?.I think its a 9/32 but Im not 100% sure.Also any other tricks from the guys that have been there done this?

Greatly Appreciated
