2nd outlet fittings

I'm trying to plumb the second outlet on my 720. The two fittings that screw into the block are JD188 and JD189. Both are obsolete. Does anyone know a Deere part number that is the same thing or know another part number to order the correct fittings from someone else. I've searched and only found one thread from back in 2010 but there were no part numbers or sizes given. Any help is greatly appreciated. I'm needing to get this done to pull a planter with two cylinders. Thanks Chris
 
Are there plugs in the block now that could be measured, or open holes?

The fittings, #21 and #22, look like common "ORB" hydraulic 90? fittings, have you checked to see if they are common ORB sizes?
 
Since the part numbers are different, I wonder if the plugs are different sizes, or are the adapters made at different angles other than 90??

I owned a 730 with dual hydraulic back about 35 years ago, but I can't remember at all what the hose and fitting setup looked like.
 
One of the fittings is a 45 angle, the other is a 90 degree fitting. Both are straight o-ring fittings, should be easy to find at a good hydraulics shop.
 

If you just want to actually USE the ports and don't have to have it look original, just get #12 o-ring boss to 1/2" pipe adapters and put your pioneer couplers on those.

Alternatively, you could use #12 ORB to JIC #12 male and get #12 female ORB Pioneer couplers. Put an o-ring around the JIC threads (which are identical to #12 ORB) and mount the couplers that way. Looks a little cleaner and a smidge shorter.
Just make sure the point of the JIC ends clear inside the pioneer couplers before you fully tighten them. You can grind off the taper if you need the clearance.
