Cheaper? New 9" or build one?
My buddy is gonna give me his ford 9". I'm wanna put a locker in it, he's recommending new moser 5x4.5 axles instead of drill out bolt pattern. Also have to get disc brakes for it. Ouch. Lookin' expensive. There's a few on craigslist That are rebuilt and have a one year warranty for $1450 come with disc brakes too. What exactly am I lookin for when it comes to shopping for a 9"? If I go with a wider axle, could i put a bigger offset wheel on there? Here's a few I found...
FORD 9 INCH REAREND, PERFORMANCE, RACE, CLASSIC, RAT ROD,
Currie Ranger Ford 9 Nine Inch Axle
FORD 9 inch Mustang Rearend

I rebuilt a stock 72 F100 9 inch with a locker and all new drum brakes. I probably have $800 in it. The up to 72 9 inch will be the right width. Make sure that a disc brake rear if you buy one done is set up for an e brake. IMHO unless you are racing, drum brakes on the rear are plenty. Remember that the majority of brake is done with the front brakes. I have large front discs, Jag IFS.

Forget the disks on the rear unless you are going road racing or hauling heavy loads all the time the drums will work better.
If you need a different bolt pattern, it probably would be cheaper to buy new axles, Strange offer street axles for <400.00 a pair, About what it would cost to have a set redrilled and broached.
Locker? Are you going drag racing?
Non of those axles in your links will fit your truck without modifications.

I would take a good look at the 8.8 before casting it aside. Since you have some concerns about the po work, the only concern I would investigate is how the spring perches were welded to the axle tube. I am assuming that they had to be moved to align with the truck spring spacing. You can put a kink in the axle tube due to welding on the perches. If the rear is currently a roller, it is easy to get at least a check for straightness. To check with wheels mounted to the axle (make sure that the wheels are straight first) take measurements from the inside of one wheel to the inside of the other wheel on the top, roll it forward rotating 90 degrees and check the same dimension on the top, repeat at 180 and 270 degrees. A difference of up to 1/8 or maybe 3/16 inch is acceptable (probably as good as factory). More than that could shorten axle bearing lifetime. That said years ago a friend bought a custom 9" from Currie for a 32 Woodie that he built. It used to go thru bearings.

You would need to find reverse offset wheels to tuck the tires under the fenders. Depends if you like wheels that look like they came off the front of a semi tractor?
