i know not mack related, but parts related.
my ford dealer had two old timers in the parts department that ran the "off the street" counter.
the dealership got complaints about them being slow, why dont you put younger guys on the counter.
but you could go in there and get anything you wanted for any year vehicle if it was available.
one day Ed was out sick and one of the kids was at his station. i needed a suspension part for my 7 litre. the kid was useless ." 7 litre? ford never made one" because it was not listed in the computer menue.
chuck overheard the conversation and told the kid to get lost, walked over the the "broken TV they won't get rid of" opened the drawer under it, put a slide under it, turned the "TV" on, and within 1 minute had the part number for the bushing i needed. 30 seconds later he had the revised part number and ordered it.
i was informed when i went to pick up the part two days later that a message came from dealer owner that all parts men required to know how to use the microfiche machine.
and it was still in use at the front counter until two years ago.
unfortunately both Ed and Chuck retired end of last year. Ed is 81, and Chuck is 78
the microfiche machine and files now lives in the parts managers office.
