When I replaced the old Chrysler piston style compressor in my '75 Triumph TR6 to a Sanden compressor I also converted to R134 with no noticeable difference in cooling. The major difference was increased performance and reduction in vibration when running the a/c. Unless you have a concours car, replacing that heavy, vibrating piston compressor with a rotary compressor will provide benefits in engine and a/c performance as well as appearance.
