That's a cool find, David.
I think Jonathan said his dad had a '60's F-150 with 5 on 5.5 hubs and 16" rims.
I wasn't aware of Ford doing it, but I would have been pretty young back then.
Jim,
Lil'Red is a '87 F250 HD, 4.10's, 1356 4x4, Zf-5, 3G, PMGR, Saginaw PS, desmogged with a Holley 80508 and Performer intake.
Too much other stuff to mention.
