8" Rear Disk Brakes

I have an 8" Ford rear in my 26 T coupe with the stock drum brakes. I would like to upgrade to disk. Already disk in the front. I have installed weld on caliper bracket rear disks before on my quickchange in another car and am wondering if there is a rotor and hat that would make this conversion possible with out spending a ton of money. I'm thinking GM intermediate calipers. Same as the front. Rotor and hat combo is the question? 10-11" rotor with 3-3.5" offset and 4.5" bolt circle. Anyone know of a stock rotor and hat about that size? Thanks

I'm familiar with the front conversion for 65 Mustang. Never did the rear.

Below is CJ Pony Parts for the 8 or 9 inch rear disk kit

This is the one from Summit >>> https://www.summitracing.com/parts/r...0aAjHNEALw_wcB

I'm just not familiar with Ford rear ends. This 8" is from a '73 Maverick. I just checked both links. Thanks. Didn't realize there were kits out for the 8". Quite a difference in kit prices from summit to cjpony. This is probably the easiest way to convert. Now if you go this way what do you do about emergency brakes? I really hadn't given E brakes a thought until I looked at those kits. Could be a game stopper.

Oh, looking closer I see the cjpony kit has an e brake. Hence the difference in price.

On the Summit kit the E-Brake is built into the caliper. On the caliper you can see the large return spring and adjusting nut. It should hook up to the cable system you have already.

You can email Summit, see what they say.

Pretty sure Crown Vic rear discs are a bolt-on for the small bearing Ford 8" & 9" axles. I used Explorer discs on my big bearing 9"...

+1 on the Crown Vic. I'm looking at that myself right now for an 8" Comet rear on my Model A. From what I've read so far, 92-02 can be installed with very little fabricating. The curved bottom part of the flange needs to be cut off to match the top; and a small spacer is fabricated to shim the bearing support.

The alternative to that is an adapter bracket on Ebay for $150, that then uses 94-04 Mustang rear discs, calipers, etc. It also needs an adapter to go between two different brake line configurations.
