They can be difficult to find, they were used mainly on the older ram's for a short time for very obvious reasons. The valve on the high side is known as a service port and the valve on the low side is known as a schrader valve (looks like a bicycle valve).
Anyways the valve you want to replace is fjc inc 2609. It's run about 99 cents on the internet. just google "fjc inc 2609" and you will find it. If you have a problem trying to get one I can probably send you one, you could replace it with the newer style valve if you wanted to but I don't really see a reason to since the newer style valves leak as well. I would recommend to replace every 6 years the hi and low side valves, the system o-rings, the drier. Be sure to evacuate the system on both high and low side with a vacuum pump that can withstand a holding vac of 28 in Hg for atleast 1 hour, be sure you evac for about 45 minutes don't evac for to long because you could actually damage components but it is very rare. If you have a large system like me which uses 6 canisters of refrigerant then it's smart to vac for about 1 and half hours.
All this aside it is hard to find the valve but not impossible. You could try a junk yard, a tip if you do go to the junk yards you will find that service valve on dodge ram van's typical year is around the middle 90's. you can remove the valve with a channel lock plier with no issues, again valves and hoses aren't to be tighten to much because it's mainly aluminum and it would strip thread easily. tell me if you come up with that valve.
