I am working on finishing my front end loader build for my Kubota B6100. I have purchased the hydraulic block adapter from Kubota (part number 70070-00385). Does anyone know what thread size the hydraulic ports are on this adapter. Just trying to source adapters if need be. I have access to a hydraulic hose crimping machine, so I will be making all my own hoses.

There was 2 different plates that I have seen, one used 3/8 NPT fittings, the other uses 3/8 O-ring boss fittings.
How you can tell the difference is if there is a taper or recess cut into the block where the fitting goes into, then it's probably O-ring boss.
