I bought my kit locally - it's from MBM - here's a link: DBK9- Universal Ford 9" Rear-End Universal Disc Brake Kit - MBM Brakes

Installation instructions: http://piratejack.net/template/img/DBK9_v2.0.pdf

I had 2 issues to deal with when installing mine:

1. I have a rear sway bar that interfered with the calipers, so I had to mount the calipers in front of the wheel, instead of the rear. That required me to use the left caliper on the right and vice versa.
2. I had to extend the connection from my e-brake handle to the cables. I suspect this was more to do with the way my car was built than anything wrong with the kit. I used a short piece of steel tubing, internally threaded 5/16" NF to make the connection.

MBM doesn't sell to consumers / end-users, but various dealers do. Here's one:

• Base kit: Ford Replacement Parts | Classic Mustang Parts | 1966 Mustang Parts - Pirate Jack
• Drilled & slotted rotors: 1966 Mustang Parts | 1967 Mustang Parts | Ford Brake Parts - Pirate Jack
• Powder Coated Red Calipers Drilled & Slotted Rotors: 1965 Mustang Brake Conversion Kit | 66 Mustang Disc Brake Conversion Kit | Mustang Brake Calipers - Pirate Jack

Other than MBM, kits like these are widely available (e.g. Jegs, Speedway, Summit, etc.), and many of them include brackets to fit most, if not all, of the different axle ends Ford used over the years.

I know Jegs lists a couple, one for staggered shock rear ends and one for non-staggered shocks.

Summit has a couple of Rear Drum-to-Disc Brake Conversion Kits ( https://www.summitracing.com/int/par...1626/overview/ https://www.summitracing.com/int/par...1627/overview/ ) but I can't tell the difference between them - likely the staggered / non-staggered issue. A phone call to Summit would sort that out quickly.
