The Stovebolt Site Forums The Parking Lot '60-'66 Trucks '64 LB original or modify?

The build tag has been painted over, but I can make out some of the numbers. 5000 : which I think is the load, 8 TD 503 (503 I know is the color) But the 8 and TD ??? and then 127 is the wheel base.
(Note: Its was a manual since there's a clutch pedal.)
