It's times like these when you start asking yourself....."self, do I really NEED this frustration and this kinda grief from an expensive hobby like these Mustangs?"  Then you got people that sell you stuff that obviously was NOT tested or checked and they got THEIR money!
Take a few days off.................Punish that bad-bad Mustang by parking it in a hot garage.....ALONE!
When you come back in a few days things will look different.

Thanks for the info guys.  I haven't taken a hammer to it just yet...LOL     I called VA this morning and he said there is some crap in the line or its that expansion valve.  He said they rarely see expansion valve's go out.  He said he would send me one out.  I did cut my on lines TKO and take them to a shop to crimp them.  The diagram on the hose routing wasn't very good on the pump in the instructions.  But all the hose fittings seemed to fit exactly where they need to go. They were size specific for where they needed to be.  Here's pic of the compressor and hose routing.  The lower hose on firewall goes to condenser.  The upper hose goes to Compressor.  Looks like that might be the pressure hose.  Has a cap on it to connect charging unit to.  The hose on the left of the compressor goes to condenser.  Im going to try to get at that expansion valve without removing the unit.  I think if I remove the Dash pad there might be enough room.  We'll see.   Thanks Steve69

I'm certainly following this thread. Wishing you well Steve.

Thanks for all the good info guys.  Im going to check the hoses first and make sure there's no issues.  Then go to check valve.  I think I might buy the $100 Ebay AC charger and vac system.  That will give me a good Idea if I actually fixed it before I waste the shops time taking it back to charge it.  Thanks again Steve69

 Hate to hear you are having troubles. Hope it’s an easy fix. I picked up a set of AC gauges from Harbor Freight a couple of years ago for about $60 and they have worked well. Advance Auto and Autozone will rent vacuum pumps for the cost of the unit and return it when you are done with it. It’s not worth the cost to keep forever. I ask for a new pump each time. If it’s a used vac pump they have on hand, make sure it has oil in the site glass. I’ve gotten a couple of them home with no oil in the site glass.

*****I got AC now***  So I took all the lines off and blew them out.  They were all fine.  No dirt or clogs.  So I put some air in between the AC lines that come out of the firewall.  There was no flow and air wouldn't circulate through.  So I figured it must be the expansion valve.  So I tried getting at it in the car.  I could touch it but there was no way to do it right or even get a wrench on it.  So I pulled the heater out and put it on the bench.  I took off the hard lines and on the pressure hose there was this rubber stop in about a half inch in the line.  There was no way I would see it when I put the lines on it.  I pulled it out a bit for the pic.  So my advice before installing the hard lines run a screw driver in the tube to make sure there is no restrictions.  I bought a evacuator and gauge kit on Ebay for $90.  That did pretty well.  I don't think the gauges are accurate.  Seemed a lot lower when pressurizing the system. I wasn't really sure if Freon was going in.  The valve that was on the Freon can was not the greatest.  I had to move the twist handle around and finally found a good spot where the Freon would come out of the can. The youtube videos were helpful too.  So my unit takes 28 oz. So I added 3  12 oz cans but I think I might of got only a few ozs in on one can.   So I think I was close to the 28 oz.  Seem really cool inside.  Thanks for the help!  Now to get rid of this vibration in the axle when coasting.  Steve69

I have figured out that all cans of refrigerant are not created equal. Most have the metal top that gets punctured with the twist in punch, works great on ththe car, not a long shelf life fo the part of a can that doesn’t get used. I bought some cans from Home Depot awhile back that had some type of membrane where the ouch goes through, added a lot to partial can shelf life, but made it wicked miserable to get it out of the can and into the car, I now avoid those cans.

All new cans of 134a now have the rubber seal on top. You must purchase a $3 adapter to use these new rubber seal cans with the old metal seal piercing valve.

It sucks that you had to pull it all back apart but glad you found the problem. It’s a lesson to all of us to check everything, even if it is new.
