What thread size to replace old style auxiliary hyd couplers w/ flat face on 7753?

[dirt ditch]

I need to know what pipe thread size of flat face couplers to get to replace the original pioneer style ends on my 1993 7753 Bobcat?

I have been using old style to flat face adapters on the auxiliary hydraulic couplers of my Bobcat. That makes them stick out past the lift arm. They are now in the way of my new root grapple so I need to get rid of them.

2 weeks ago my wife drove a hundred+ miles to the Bobcat dealer where the parts guy sold her manifold style couplers which are wrong for my 7753. Today she drove another hundred+ miles and exchanged them for the right couplers.

Bobcat part numbers for the couplers are: Male - 6676444 / Female - 6676446
