Some more info on A/C compressors:
This info was posted in the 70-73 section regarding date codes on the compressor decal:
The decal off my original compressor read
120761 which breaks down to:
12-Dec
07-day
6-1976
1-1st shift
My car was built this same day according to the broadcast sheet.
I replicated the stamping on my repro decal using 1/8" number stamps. The original decal would not come off intact, even with a bit of heat.
This is the closest repro decal
