AC Missing parts
can anyone tell me from the pics what hoses or parts i am missing, and maybe a place to get them, along with some brackets. And if anyone knows the thread pitch and dimension that connect the hoses to the compressor please let me know
For the picture below i know i need the other hose that connects to the drier, can anyone point me in the direction to get it? preferably used, i dont want to buy OEM too expensive.
Below i have some duplicates i think, is there a need for both of the hoses in both sets?

It would appear that you do have some duplicate parts. Look at the parts diagrams to find out what you're missing.
Have you verified that all your lines will fit together properly? Kinda hard to tell for sure from the pictures, but it appears that you have a low pressure line from a factory R-134a car and a low pressure line from a factory R-12 car. The manual indicates that the fittings which connect the lines together are different depending on the refrigerant, as well as whether the system is the MANA or Nippondenso type. So potentially you've got four different sets of fittings. Who knows what fittings they put on that GhettoBrand [tm] condenser. Speaking of that condenser.....your system performance will be terrible with that condenser....it is a tube and fin type which is SIGNIFICANTLY less efficient than the stock parallel flow design, although much cheaper to manufacture. Return that sucker and get a stock condenser, espescially if you're planning on running R-134a when the temperature is above 80 degrees outside.
I'm sure crud has gotten into all those lines be sure to flush out all the lines and evaporator with a good A/C flush solvent. You'll have to remove the expansion valve under the dash to do this properly. You'll also need run a good bit of new, clean compressor oil through the compressor while slowly rotating it by hand. Then drain and refill with 1/2 to 2/3 of the factory specified amount.....no telling what sort of gunk is in all those lines, and the compressor. Also be sure to replace the receiver/dryer. That one has been open to the atmosphere for who knows how long, and the desiccant bag will probably pop if you try to use it, filling the inside of your system with little sandlike desiccant particles.
You can't half *** A/C repairs, espescially on these cars since they are such small systems. You have to have the proper tools and the proper knowledge....if you don't you're going to be constantly replacing parts, and adding refrigerant.

The receiver/dryer/accumulator is NOT the same as the evaporator.
The evaporator is the heat-exchanger INSIDE the car, and the condenser is the heat-exchanger OUTSIDE the car.
You do have an evaporator, don't you ?
That is, I hope your car came with A/C, or are you adding/retofitting A/C ?
If retrofitting, you need an evaporator . . .

not retrofitting, im sticking with R-12, and as for the evaporator... well its been a long time i actually forgot about that, its been about 4 years since having worked on an AC system
im sure the evaporator is still inside, when i bought the car the ac was completely torn out.
