Suburban A/C fix + Vintage Air?

I'm late to this as well. But 2 things. Definitely only use AC o rings. and 2, if you do 134a be sure to get the biggest parallel flow condenser you can fit. Okay, actually 3 things. I would use a compressor that's in the 9.5+ cubic feet / revolution area. I don't know if the trailblazer accessories allow it but something like a denso 10s17F or a 10s20F. Many of the compressor you find will be sized for a single evaporator system and will likely be a bit under sized. I suggested the 2 above as they are bigger than your typical Sanden from a cubic feet per revolution standpoint.
