[C10 - C90 Bill]

For Gauges, some are Standard, others may be Standard for a particular application, others may have been Options. But that said, my '71 9500 with the 637 V-8 Gas was "loaded" with Gauges. Although there still may have been an empty space or two. I would say that my truck's Gauges were Standard as I can't picture the cheap company that I worked for paying any more than they had to, lol. That's the main reason we got the 637, as it was probably about $1000 or two cheaper than the Detroit.

The other changes may just have been a year newer change. If I remember correctly one of your trucks is a '74 and the other is a '75, but maybe Bob or Dan can add more info to it than I can.

I'll have to try to find my '67 7500 pictures someday. I took a bunch. Hopefully the Dash as well. I owned it from '86 to '90.
