I will sometime get around to finishing my ls 5.3 ac system. It will be basically a trailblazer ss 6.0 ls compressor/lines/condenser and make it adapt to a stock ac box. The condenser in my hands fits nicely in the opening. You would need to adapt/tig weld the ends to match what you have. I figured that the trailblazer interior volume was more than our truck cab so it should be ok. I'm using the stock 5.3 clutch fan and a 68 fan shroud.

Why use a trailblazer compressor? Because the suction/discharge ports on the compressor are positioned front to back and i won't need to notch my frame for the lines.

With your system switched to r134 your poa valve i believe will need to be adjusted/replaced to work right, but someone will chime in that has been there and done it, or search for r134 poa valve articles. Good luck!!
