So after doing the headgaskets, the IP puked, so I did IP and injs and it's been running good overall. Time to fix the A/C Found both lines going to the rear a/c unit leaking. was going to just order lines for a Blazer/Burb non rear a/c but decided to see price and availabilty for the rear lines. Only 2 of each left in the counrty and discontinued....300$ for both(high and low press). I would cost me almost 150 any way to change over to no rear a/c so I said screw it and bought them. Pass innner fender well was rotted and had to come out to change the lines so put a new one in as well. A/C blows nice and cold front AND back. Now if I could just find a factory rear heater. The guy removed it but the wiring is still there. That won't be an easy find.
