No, R12 will go through that line just fine. The service fitting for the AC is on the top part before the bottom hard line fitting.

wow....that's a really good price. Yeah, that was the picture I noticed it in, haha. looks like I'm gonna have to convert to r134a now though hah

Nope you will definitely have to move the AC line if you want to keep it. What I did was take the line to a hydraulics shop and had them cut it. They cut it at the top where it has the o-ring and fitting, and they cut it down at the connection to the compressor. Then I had them use 2 feet of high pressure hose with compression fittings on each end.
That hose is pretty rigid, but it is flexible enough so that I could run the line down the front of the fender and back to the compressor. This gave me plenty of clearance for oil drain and other turbo components. You can see the line at the bottom of the pic below. Best part of this solution was they only charged me $16 to make the line!

Very nice; good to see the progress. What did you use to move the AC line? I would very much like to keep AC, but that doesn't seem particularly possible where the line is from the factory.

So, I put the 4.10's back in the car and removed my turbo manifold and had it rewelded (it had cracked EVERYWHERE). No wonder I had so many exhaust leaks. Got the car back together today and took it for a short spin. It's running a bit rich now that it doesn't have those huge leaks, but holy hell does it spool a helluva lot faster. I should have taken pictures of the leaks... lol around the turbo flange had cracked 3/4 of the way around the circumference.
Going to take it to the exhaust shop on monday to have them weld a joint into the downpipe/exhaust area so I don't have to keep dropping the entire exhaust anytime I want to service something. After that I will post videos of how the exhaust is actually supposed to sound with no exhaust leaks. Stay tuned.

Do you do your own MS tuning? I've basically got my NA map down now, with 12.2-12.7 AFRs at WOT and a tad over 15 at a cruise. 27 mpg city with the MS currently :). and the PWM idle works great. It lasted through an HPDE last weekend with no problems at all and wayyyy more midrange than it ever had before, so I'm happy
You're pretty rich for a NA setup at WOT I think. I run 12.0 @ 12psi boost. I would think you'd be better served in the low 13's? Could be wrong.

How does the exhaust sound? I need to change my rattling muffer, would like something a little different.

LOL the right balance between power and reliability is right before parts start breaking. ;)
