Omar, when you get ready to do the hoses, charge, etc. I have all those tools here including crimpers for the A/C lines. My dies are specific to the smaller less bulky fitting style, forget the actual name for them off the top of my head. I have gauges and vacuum pump, freon recovery system, etc.
The bulkhead idea sounds cleaner than the mess often used. I did that on my JK with a/c and heater separate. There are a couple of other sources for those bits. I'll try and get into my archives and see what I can find.
