All the hoses were replaced they didn’t leave me with the standard charging port they left that one do you know what the adapter is called to use a regular gauge manifold on it?Yes, those are the two ports.
they are all you need to charge the system. Standard R134a hookups.
You will want to go over the entire system and make sure all the fittings are snug. Not too tight, because they are o-ring seals. My truck had the MAK (Marine Armor Kit) removed from it before I purchased, so many of the fittings were loose from where it went through the armor.
While you are at it, since the system isn't charged, it might not be a bad idea to go through and replace all of the o-rings in the system.
Red dot bagged O-Ring assortment 70R5020 , cost $6 on ebay.
The receiver/dryer isn't a bad idea either if you don't know if it was open to atmosphere at all. Mine was still mounted properly, but had been installed backwards, so double check it is facing the correct direction for system flow.

Double check your compressor, it should be a Sanden, and you'll want to use SP-15 compressor oil to lubricate the o-rings and fittings, supposedly not compatible with standard PAG-15 oil.
The high side port is the same as a standard GM thread in port, can be bought for pretty cheap anywhere (mine leaked a little)
The low side port is a hose fitting, not as common but still pretty easy to acquire on ebay. (I paid like $6 for a replacement)

be aware this fitting needs # 12 hose
The hoses and fittings are relatively cheap for these systems, so replacing any of them that show issues like cracking or corrosion is much easier/better to do before you charge up the system (I replaced every hose and all but one fitting, and ended up having that one fitting be the one with issues and so needing replaced later, and it was the high side charging port, under $10)
