The stock Tube & Fin type condensors in any vehicle have a poor track record when converted to 134a. High head pressures & poor performance.
If you are willing to make a change to a newer style condensor, you can have great performance. Newer cars have good A/C with smaller compressors. If you keep the RV2 you can have better cooling than it had when new.
The condensor from a 2006 CTS-V is the right size. It is 22 inches across the core, about 16.5 high, and has great mounting tabs. The dryer is part of the condensor, so that will clean up the plumbing & engine bay. The dryer element is replaceable.
Hope this helps.
