I have a set (2) of used Dodge PW/M37 open differentials with 4.89 installed. They have PW yokes on them, which swap out for M37 yokes. They are ready to install. They will increase your road speed while cutting down on engine rpms compared to original 5.83 gearing.
Shipping is $$. Figure $100 each b/c ~80lbs.
Location is near Hershey, PA.
The price is $1000 for both or $1000 for one;)
Remember, new 4.89 gears cost over $450.00 per axle and then require installation by a rare person with tools to work on these 9 5/8" rears- $$$$. Mine are bolt in.
I will post pics later this week.

The following are pics of the 2nd differential. Clearly this was the back differential. Like the other differential, the bearings and backlash are great. Unlike the other which seems to have no wear on the ring gear teeth (still has blue finish on wear points), this has normal shiny wear patterns. Note that 5-6 teeth had slight surface rust that wiped off with an oily rage to reveal slight frosting on the wear surface, but won't effect its use. I would put the 1st rear in the back of the truck and the 2nd differential in the front axle housing as the back axle gets most of the wear.
