Oil plug size on block?

[Kenny_Kline]

Looks like there are 3 threaded holes that lead to oil on a 6bolt block. I need to block these off. Does anyone know the size of plugs they are so I can order them? I wasn't sure if there are anymore. I know there's a couple on the front case that have bolts in them and red loctited in. And one is for the transmission but the 3 that I think need to be blocked off, 2 are on the front balance shaft and one is in the rear balance shaft. Here are the pics of the 3 I found that I think need to be blocked. The 2 in the front shaft are smaller than the 1 in the rear shaft

They are all BSP 3/8 and 1/8 I think and the balance shaft inspection hole is a regular bolt m6 or 8 by 1.25.
