Wanting to take the open differential from the 74k mile F150 and put an
Eaton True-Trac in it and also change the gear ratio from 3.55 to 3.73.
Doing it myself should be about $1000.
So, I'm wondering if the rear axle part numbers are different before I go
and rebuild the rear axle in the '91 F150 and then go and try it put it in
the '91 Bronco and find out the spring perches are different or some other
non-visual-something is different. :/ Want to to know now before I go
and rebuild an axle for my Bronco "that ain't quite right".
The rear springs are a different width, but more important, are the perches
set at different angles or some other crazy Ford-part-change was done?
Those sorts of changes will be in a part number change, seems to me?

ps- One more "one wheel wonder" bites the dust?
...or "bites at, but misses!" the dust?
pps- The axle in the Bronco has got Traction Lok
and still works good and it'll go in the F150.
ppps- The 8.8" in the F150 is super sloppy with slack!
