Ford 8.25, or 8.8?

Hi

I have a friend who has a 1979 bronco...it has the original rear end in it...but would it be an 8.25 or an 8.8? Or a 9?

Any one know if it be worth picking up to swap out my AMC 20 from my wide track CJ7?

Thanks!
Patrick

Hi

Well, just as told...it is a 9"...price is right...free...so I think I'll pick it up.

Any cost estimates on having it shortened? I measure ~58 from drum to drum on the 9 and ~50 for the AMC20

Thanks for letting me think out loud!!

Measure wheel mounting surface to wheel mounting surface. If this is 58", sounds about right to go with a Jeep wide track front. If this is the case, I would let it sit until you find a wide track (or other replacement) front and swap both at the same time. This way, if you do break something, it's not a custom part that only fits in your housing.

Is this the only hammer you've got?

If you find an older 9" Late 60's early 70's??? From an F100 (Not sure the exact years) it'll fit perfectly under the Jeep.. I gave my 9" away and replaced it with a 14 Bolt. 400+ft-lbs of torque and 42" swampers matched with a lead foot isn't a good thing

We use Moser [or Currie] for 9" stuff. Moser currently charges $120 to narrow your housing. But they sell a brand new HD housing with thick tubes and large bearing ends in any width you want for $325. 172 mph barrel roll in a race car destroyed about everything but Moser's diff. It was still straight and reused. If it can do that it will handle any rock you can find.
