What size are the auxillary hydraulic valves on a Case CX50B?

I built a hanger for our McMillen auger drive and need to make a set of adapters to plug it in. I need to know the size of the o-ring fittings to go into the aux shut off valves. I have a thumb on it, but it has smaller lines with #8 JIC fittings. I want to connect to Case flatface skidloader couplers that are 1/2" pipe thead.

thanks,
