Thanks for the info. Both my 2.3Ts have the Turbo Coupe serpentine setups already along with 3G alternators. The only bracket I'd have to fab would be to hold the compressor.

From my searching, the Sanden is replaced by 4664 now? Does it come with a V-belt pulley/clutch that I would have to change to serpentine pulley?

Unless it's feasible to get the HR980 compressors functional? I read anecdotal data on how well the HR980 works with 134a.
