Re: '67 A6 A/C compressor casting numbers?
Russ, thanks for taking your time, checking, and responding. There's adequate documentation of block and head casting numbers, but I'm having difficulty in the compressor area.
Unfortunately, neither compressor has any original Frigidaire labels. The back plates are identical except the 406 casting has an additional pressure relief on the low side, as well as the protruding high side pressure relief valve. The 302 only has the high side protruding pressure valve.
Putting a 6550133 label on any A6 would appear correct, but not essentially correct. Could there have been more than one casting that was used on our '67's with the 6550133 Frigidaire tag identifying them?
The 406 compressor would be an October 27, 1966, two weeks before my build date, but I'm not sure of either casting number as being correct for our Camaro's.
