Do you happen to know what the hydraulic pressure and gallons per minute are supposed to be for the front hydraulic arm?

I know this is an old post but maybe someone will still look.
Question is: Are these couplers available "aftermarket" I have tried looking on amazon and purchased a couple that don't fit? OEM parts are like $100/ea

Would these fit? and if not what ones might? any help is appreciated
