I recent bought my compressor. I will send you a private message with where I bought it. I called the company before hand to make sure they had some in stock before I ordered. The guy told me they had a few on a self in KC. I had mine in a couple of days.
I managed to fit the compressor into the space behind the filter box, but that was without the pancake filters on the compressor in stall and it was squeezed into the wire harness enough to make me nervous about tearing it. I think I have come to the conclusion that it isn't going to work. I don't really like the way that Rago's driver's side mounting plate goes over the fuse box. So, that's a hard no. So, I guess I'll mount it in a small tool box with some wire clamps to attach it to my battery when I need to use it until I am ready to give up the S&B filter for a snorkel.
Here's a link with a picture of how tight it is:
