The 54/55 truck uses the same manual-wind clock as used in a 53-54 car. Will the electric clock from a car fit the truck's housing?

This shows the 1954 Flat-Face Cowl gasoline gauge as being different.

This shows the 1954 Flat-Face Cowl ammeter as being different.

The 137" wheel base school bus shared the same equipment as the 137" Flat-Face Cowl. It does not look like other school buses shared the FFC gauges.

Thanks for your post about the differences in 54/55 gauges. I now remember that there was recently a 54/55 NOS FFC fuel gauge listed on eBay.
