Mike..thanks for your help..got some more info..looks like serial number is 4553333..and casting number is 837231. There also is a G-23-4 near the cast number. Looks like a 33/34 hybrid.
Rear spring mounts center to center are 45"..with 9 leaf springs. I have the wood extension which appears original that extends 15" past edge of door..running boards are 61" from fender..all appear original. Would be nice to know history of truck..lotsa questions. Thanks again
