ac line

[xero1]

I have an 89 s13 with a s13 sr20det black top compressor(r134) and was hooking up the ac. This is what i did, i cut the end off the stock lines that goes to the compressor and use the ends connection that hooks up the the new compressor. Now that i got the lines to hook up the new compressor, i only have a low side charge fitting and no high side charge fitting. How can i install or get a hight side charge fitting?

Would the stock hi side line not connect uncut? I have never seen the blacktop compressor but on my redtop I could connect the one line, just the low side needed to be modified because it hit.

none of the stock 240 ends could be connected to the sr20det blacktop ac compressor, so i cut the end off and replace them with the sr20det blacktop ends, now they bolt up the compressor, but i there is only a low side charge fitting on one of the new ends that hook up the the compressor(no high side charge fitting). the old 240 had a low and a high side charge fitting at the end of both ends that hook up the old compressor. i need to find a way to install a high side fitting, so i can get all the air of the system when i pull a vacume. any suggestions?
