removed the front clip tonight on the crew cab,found a build tag

27-66 S 704696
F1 3-1 110
HTR1 LH DOOR LOK
GOVT JOB CHANNEL BUMP



also found tag on rear seat frame

Orrville metal specialty co

model serial
110-140

I forgot to write the serial # down

I assume the 110-140 means
a reg short bed wheelbase is 110
this trucks wheelbase is 140

Any info on the build tag?
