a/c compressor ?

No. V2 (9.45 cubic inch displacement) on the small cars, RV2 (10.5 cubic inch displacement) on the big cars. Anything else is aftermarket or not for a Mopar. The dealer-installed Mopar systems used V2 compressors; virtually all non-Mopar aftermarket setups (Mark IV, Frigi-King, Frigette, etc.) used a brick-shaped York (aluminum) or Tecumseh (cast iron) compressor. Those are 2-cylinder compressors like the V2, but they're inline-2 rather than a V2 configuration. The only Mopar A-body A/C setup that did not use a V2 compressor was the 1961 slant-6 setup, which used a Tecumseh HG-1000 cast iron 2-cylinder brick-shaped compressor.
