What I found for the part number was in the factory parts book and it was MB 044842
This one will work with the 2WD brake system?
MB316678 - PRESSURE METERING VALVE
Pick-Up
That would be great! But different part number?

to further complicate and confuse - in 86 there were both 1st and 2nd gen models made - to 2/86 1st gen, 3/86 on 2nd gen. And 1st gen 86 trucks have some specific parts that were 86 only, like gas tank sending unit, but the tank is the same as 79 - 86. Part numbers change all the time for Mitsu parts - I have seen 6 different part numbers for the same part many times at the dealer.
My search found that part number as this. Your going to have to get your feet wet sometime. It can always be sent back also.

I've exhausted all possible sources I've found for trying to order a brake proportioning valve for the D-50. Does anyone have one which works for sale? Or do you know where to get one for sure? I'm getting tired of ordering them, making the payment, and then getting an email that they don't have it and will refund my charge someday.
Try Capitol Clutch & Brake in West Sacramento
They have a non-adjustable (which is good) one which has one line in and one line out for rear brakes, but one line in and two lines out for front disks. The original appears to have one line in and one line out.
Don't know how that would work out.
Are the original ones rebuildable in any way?
could you put a plug in one outlet that is not being used?
Check out this article on a 1980 brakes issue. Maybe give you some ideas.
