Installing a/c lines. Ok so I finally decided to fix the a/c in my car. It was leaking from the suction hose that runs from the condenser to the back of the compressor, and is connected to the discharge hose. Well I was able to get the old lines out but getting the new ones to fit is becoming an aggravating challenge. I just can't seem to get them to line up with the holes in the back of the compressor. Does anyone have any tips or tricks to make this job a little easier? I can't find anything on this subject besides people saying the job is "difficult".
I've never done this job, but having done other work on my '96 Z/28, I know that space is really tight in that area. MAYBE if you're able to loosen the bolts that hold the A/C compressor in place, you can shift it one way or another, you can get a better shot at it??
Honestly there's really no easy way to do it outside of constantly trying to catch a thread while pressing the lines against the back of the compressor. Make sure you don't rely to heavily on the bolt pulling the lines into place or you might end up stripping it out.
Maybe try zip tying the lines into place against the compressor? Then cut away zip tie after you've caught enough threads.

Installing a/c lines. The suction house comes from the evaporator (dash), the hose from the compressor to the condensor is the pressure (discharge) hose.
When I replaced my pressure hose, I found the part that loops up towards the exhaust was hitting my #2 header pipe. I had to do some slight bending to that pipe to get it installed and have just enough clearance not to hit anything (that header pipe).

I bought that host cluster at Autozone and found out the hard way the ports would seat into the compressor, but the bolt hole did not line up. Ordered one for Rock Auto that was a slightly better fit, but still had to fandangle the bolt into the back of the compressor. From what I remember I believe I had to take the compressor completely out to get the hose cluster into place.
