Needed a tiny little tool to get the fitting off, my friend's a mechanic and I stopped by his shop today and did it outside his shop, I just had to take my battery terminal off because I have a bunch of extra wires there for my stereo, but normal setup probably doesn't need to do that. Just the brake booster side was tough because of that, other side was super easy. I swapped them and I'm motoring around with the new one. When I install hot pipes again tomorrow, should make it that much easier.
