What axle in the rear of an early 99 f250?

[Matthews]

I am curious what the rear axle is on this truck. It has one caliper on the front side and one on the rear side. It is an early 99 7.3 manual 4x4.

Thanks

Yours might be different, but I think mine is a ford 12 bolt

Ford 12 bolt

Should be a Sterling 10.5, could be a 10.25 though.

I think my 2000 has the 10.5 but both calipers are mounted on the rear of the axle on that so since this has one front and one rear I figured it must be a different axle. I thought maybe the 10.25 but don't know for sure.

I will try to get the vin in the next day or two and maybe we can confirm.

Anyone else know what it should be?

Guess I learn something every day. Didnt mean to make a stupid comment. I had assumed it was a ford rear end and had 12 bolts so thats what i said. Mine does have 12 bolts and appears to be a sterling 10.25

All SRW Super Duty trucks had the Sterling 10.5 rear end.
