I don't know of anyone that makes a full kit. There is also a third bolt on the right rear of that AC box that you can not see in these photos, I wonder how he mounted that one.
I mounted mine a tad further back. Which had it's challenges. There is a fair amount of fab work in getting one of these systems to work and fit within the chassis. I built my own compressor mounts, condenser mounts, welded up the old HVAC holes, made new HVAC holes, made up the hoses, made brackets to mount said hoses. Other than welding there was a lot of figuring out and fitting parts. However, I am LS swapped and have other packaging issues. Pancho is a cool dude, me will probably share dimension with you.
You could probably get pretty creative with some angle iron, flat bar, and make a mostly bolt together bracket solution for the box under the dash. Or put your parts together and have a friend weld them. Heck mail them to me and I will burn them together for you.
