Well, found a good used '87, obviously has a newer motor/transmission (302 MFI and a 5 speed overdrive xmission)
Can't find much in the way of readable data tags anywhere yet.
VIN tag in the door indicates the axle ratio code B9, I believe that the axles are the original. The rear is huge compared to the one in the '72 F250 I've had for eleventy million years. Could it be a 1 ton? Full floating, of course, huge hub, 8 long lug studs like it would take at least duals. A Ford 10.5? There is a small tag held on by one of the cover bolts, S127G on the top row, 551023A29 on the bottom row, numbers don't look like anything I can find in Chiltons. They don't carry the detail they used to, can't find the tables I need looking on the internet yet.
Any help out there for me without yanking the HUGE cover off of this thing and counting gear teeth?
Appreciate any help in advance......
