What are the last 6 digits of the Vin#'s
77 was a transition year & the so named Highboy ended.

I suspect one is an early built truck & the other is a late truck.

The numbers will tell the build dates.

Hey Million, were the F150's set up as highboys also? I always thought it was only the pre-77.5 F250's that were highboys. Pre 77.5 250's had 5 or 6 leaf packs up front, 77.5 they went over to the 2 leaf pack up front on F-250s but didnt the 150s run a coil spring/radius arm setup similiar to the new '05 super duties from the early 70's (73ish?) through to 79?

Just a thought, maybe the second truck is an F250 with a D60 up front?
