Factory A/C would be an option, not an accessory. Since the trim tag indicates A/C, Fisher Body would have any records. But the dealers also offered third-party A/C units, which would have been an accessory, not an option, therefore complicating the ability to get a count.
"Factory" A/C could be installed at the factory or by a dealer, thus even if numbers were available it would not include all "Factory" A/C units UNLESS the GM kept track of number of "Factory" A/C kits soldAre there any records of the numbers of '57's that were produced with factory air conditioning?
What about 55-56. Can it be correct to have a A/C even though trim tag is not on driver side. Can it be said that it was a dealer accessory?Yes A/C could be a factory unit installed by the dealer and therefore an accessory and therefore have accessory A/C installation instructions. But the trim tag would have indicated that it came from the factory without the optional A/C. Factory-installed A/C was an option, not an accessory, and therefore did not have installation instructions because it was already installed, and was indicated as installed on the Fisher Body trim tag.
Back in the day we found Positraction on the turboglide equipped cars. The GR (grade retard)on the gear shift selector was easy to spot rather than crawl under a car that had no wheel on it in the junk yard.JB56Did the 57's come with positraction at all. Peter
