Pic 1... AT CONDENSER.. Pic 2... NOT A COUPLING, RUBBER FOR CLAMP... Pic 3... NO PINCH MARK OR DIMPLE...
Pic 4...NEW ACCUMULATOR, & IN BACKGROUND THE TUBE WITH NO PINCH MARK OR DIMPLE...Pic 5...UP FRONT GOING TO CONDENSER.....
I COULD NOT FIND ANY PINCH MARKS ANY DIMPLES ANYTHING THAT MIGHT HOLD AN ORIFICE TUBE IN PLACE. I'm wondering if the orifice is even in that too I'll just buy the whole tube but if the orifice is not in it then that's going to defeat my whole purpose. I am by far not even close back to square one but I am still kind of confused. I hope this helps.

Yeah, the orifice tube *should* be in one of the lines. The part description should mumble something about it..... I would think....

​​​​​​
This is what it offers me... It appears that you just cut the tube excuse me the line rather and insert this orifice tube. So this is my logic.. remove the tube again and push a soft wire into the tube and see where the existing orifice is located IF IN FACT THE ORIFICE IS EVEN IN THAT TUBE. Push the wire in both ways, make measurements and calculate the center of the existing orifice and cut the tube at that point. IF THERE IS ENOUGH ROOM TO INSERT BOTH ENDS OF THE REPLACEMENT ORIFICE. I can figure that out. However... What if there's no orifice at all in that tube?

There has to be an orifice tube, or something similar somewhere, that's how a/c works. From the service manual:

The fixed orifice tube is located in the outlet line of
the condenser. It has filter screens on the inlet and
outlet ends of the tube body. The filter screens act as
a strainer for the liquid refrigerant flowing through
the fixed orifice opening. O-rings, on the tube body,
prevent the high pressure liquid refrigerant from bypassing
the orifice. Adjustments cannot be made to
the fixed orifice tube. I f i t becomes clogged or damaged,
replace the fixed orifice tube.
The fixed orifice tube assembly is the restriction
between the high and low pressure liquid refrigerant.
It meters the flow of liquid refrigerant into the evaporator
core. Minimum evaporator temperature is controlled
by sensing the pressure within the evaporator
with a pressure-operated electric cycling clutch
switch. The pressure switch controls compressor operation
as necessary to prevent evaporator freeze-up.
The fixed orifice tube should be replaced whenever
a compressor is replaced for lack of performance (internal damage)

So, it IS replaceable by itself, and is in the outlet from the condenser...... If you disconnect the line, you should be able to see it....

The condenser is brand new....I also removed the new condenser and blew it out with the rest of the pieces. The FIRST shoptech that I took it to he said it was in the condenser so when I took it apart and was blowing everything out I did look in the end of the tubes matter of fact... And brother I didn't see anything. And like I said the condenser was brand new out of the box. However I can and will pop it right back off of there there's nothing to it and take another look. Like I say I still have to buy the two new switches and the three new Schrader valves and open the system back up anyway.

I suspect it is in the line that connects to the condenser outlet.

Oh okay I understand I'm sorry I edited my last response before reading your response my apologies but like I say when I open that system I would take a look at everything again.... Just like the switches and the Schrader valves I'm going to buy that from a local auto supply instead of ordering it online and I would just buy the orifice at a local supply as well. Man I appreciate your time on Saturday helping me out too

The "o" tube should be at the first connection outta the condensor. At a guess, it's possible that when you blew the lines out, you mighta forced the old one up into the tube?!? Either way, I believe that's where the "o" tube goes.

Okay let me be correct about this so you are saying it is in the condenser itself... Or it is in the aluminum tubing that connects to the condenser? Because when I blew them and flush them each piece was taken apart and independently Purged. Also, how large is this orifice we're talking about? it appears from the photo 3 or 4 inches long. Thank you sir for your input.
