The 8.8 and the 9 inch are both good rearends. They got away from the 9 inch because of fuel mileage, the 8.8 is more efficient.
Either rearend should bolt in if it comes from a 80 thru 96 f150. The 9 inch will be found in the earlier models. Double check the length of the nose on the different rearends, you may need a longer or shorter driveshaft if you change from the 8.8 to the 9.

You mention "Locker"...do you mean a detroit locker or a traction loc??
I've had a Detroit Locker before and personnally would not do it again for any street application. For straight line racing they're great.

If you get a Detroit Locker,make sure you upgrade to Alloy axles.I snapped an OEM axle shortly after installing a Detroit Locker in a 9 inch.Dutchman Axles makes a strong inexpensive alloy 9 inch axle.

I would have to agree with 82f100460, a locker for every day driving isn't the way to go. Unless of course it is a selectable locker, either air or electric. A good limited slip would be a better choice.

Well none of the selectable lockers are "cheap" IMO. Any one of them are going to cost $700+ not including installation so add another $250 or so. Then if you decide on the air locker you'll also need some kind of air supply to operate it. So all included your looking at $1000+ easy. The electric would be about the same minus the air supply but, they have kind of a reputation of not being that good, don't know because never owned one. But Jeep and Toyota both use electric lockers so maybe they got them working better.
