Thread: Ford 9" rear end/disc brakes donor car

Tweet

What is the easiest andcheapest way to set up a Ford 9" rear end with disc brakes.
1) What is a good donor car?
2) What width do I need for a 32 Ford?

Ford Motorsports has a conversion package from ford explorer around 300$ with internal parking brakes

Does that give me the correct width?

Try to find one out of an early Ford Bronco. They are just the right width. The website below is a good reference for 9-inch Ford widths.

Thanks. Great website. WOW. Still trying to find a donor type car for the dics brakes, Lincoln maybe?

Thanks StuCool. You responded before I did. Good input. Also the width of early Bronco - 58" at wheel mount flange?

For a fendered 32
Most rodders ... want a rear end that is 56 to 58 inches wide ... measured this way



Unfortunately ... the only Factory setups that narrow are the 57/58/59 Ford car rear ends and the 66 to mid 70's Broncos. The Broncos have the larger 5 on 5.5 wheel pattern ( think Ford pickup pattern ). They are 58 inches wide.

TCI sells their 32 chassis with a 56 inch 9 inch under them. They come from Currie and are narrowed units. NO stock 56 inch wide units ever came from Ford.

This is a 56 inch wide 9 inch under my 32 3W.



And now with the fenders on ...



This is a 58 inch wide 9 inch Bronco rear end under my 32 roadster



Both space the rim out about the same but the 32 roadster has 1 inch per side LESS offset than the ones on the 32 3W.

Some of the Lincoln Versailles ( 1979 or so ) are narrow enough ( with a proper back spacing rim ) and are 9 inch units.



Think fancied up Ford Granda

They come with factory rear disc brakes. BUT ... I would not use one because the brake parts are VERY difficult to find and VERY EXPENSIVE if you do.

Hope this HELPS

I have been provided with alot of info on Ford 9". Thanks. I am now looking for a 9" from a 66-77 Ford Bronco 58" wide or 77-81 Granada/Versailles 58 1/2" wide. Next I plan to get a conversion kit to use Ford Explorer disc brakes. Then for a good highway gear maybe a 2.75 ratio.

1) What Fords commonly have a posi/limited slip rear end?
2) What rear end ratio is commonly used in a Ford Explorer?

There are a couple vendors on EBay offering Disk Brake conversions. Some are just brackets and you go to Pick n pull to get Cadillac Eldo calipers and Crown Vic rotors. Others are more complete and just bolt on. Summit Racing also sells a complete kit as does Stainless Steel Brakes. If you do a Google search you will find lots of brake options, once you locate an axle.

I have beat the heck out of my 8.8 that I installed in my Jeep. It has 4.56 gears and a Detroit locker.

Flordia--- Got a brand new set of the adapters ( been layin around in the box for about 5 years if ya need them.

Do your research well or it can get expensive - there are at least 3 axle tube flange bolt patterns along with the different bearings that they use as well as at least that many axle shaft protrusions. My rear diff is a smooth back '57, but like all of the very early versions through, I believe '61, has a "non standard" axle protrusion. I used a small bearing flange Wilwood setup then made up the proper spacers to fit the calipers to center of the rotor

Didn't get it.
Call 928-445-RODS (7637)

the grenada/versaille rear probably would have excellent chance of being a limited slip, disc brake with paRKING BRAKE AND A 2xx gear ratio

and the 5 on 4 1/2 bolt circle---the bronco probably will be 5 on 5 1/2 bolt circle and ration high 3xx or 4 xx
