10-4, I will start with removing the ABS module and master. Worst case I will resort to yanking the booster if needed.

I have all new line sets from GM so all I need to do is unbolt, wiggle out and wiggle back in.

My CPS MA1234 gauge set and Robinair 15500 vacuum pump come in the mail tomorrow so I can start ripping into to this saturday. Boy it will be nice to have AC once again, lol its been almost 3 years!
