bearing oil passage plugs thread size

[wagoneer]

 

Anybody know the precise thread and plug size for the oil passage pipe plugs? Picture borrowed from the great late @Don Coatneyfrom way back in 2008

The 5 plugs/fittings on the block side are 1/8" npt plugs.  National pipe thread. Very std. size.

 

The others ( ends ) I cannot say this moments.

 

Hope that is some help.

The ends are 3/8 NPT.
