What is involved in adapting Ford Explorer rear discs to an early car 9 inch rear end?

Here`s another option http://www.midnightdsigns.com/Mustang/Rear_Brakes.htm

I have one on explorer but I`ll have to find it.

As I remember . . . the Explorer backing plates have the same bolt pattern and center hole as the large bearing Torino axle housings. All you should need is a complete set of Explorer brakes and the spacer that goes between the axle bearing and the axle flange. A complete kit would look like this:

The spacer is critical. If you don't use it, the axle can move in an out of the housing by about 1/4". Not good.

What I don't remember is how the brakespace offset worked out on my '34. (That's the distance between the axle housing flange and the axle flange with the axle fully inserted.)

Thank you Henry Rifle. Since mine is probably a small bearing, I may have to do some modifications to the mounting flange.

WillowBilly3 you also may need to change you proportioning valve if your running front disc rear drum right now. My conversion to front disc came setup with a valve on the master cylinder to pump out more pressure to the discs and less to the drums, also came with a power assist for the disc drum setup.

Thanks stovens. I am actually building a system on an all handbuilt rod. It only weighs maybe 1800# and drums would work fine but all my rear end has right now is drums and backing plates, no guts, parking brake cables ect. I have S-10 style calipers up front on Aerostar rotors mounted to an early Econoline solid axle. If I go with rear discs, I would use a 67-76 Corvette m/c and a manual proportioning valve. I have access to a couple Exploder rear ends for cheap.
