I have the chance to buy 49 3100 with a dump bed, a southwest truck, great patina, little to no rust-except western rust :-), all original, no wrecks, not running, original 6cyl in it, all pieces there, they are wanting $5000 for it, good price? I can't seem to find any info out there for a dump bed option on this year? Do you have any suggestions? Thanks for any feedback.
