This has probably been discussed numerous times but I have been in hibernation for a while and need some help. I have a 69 Plymouth Fury III convertible with power drum brakes all around. I purchased a donor 72 Fury III 4 door for metal and my friend wanted the drive-train. The donor 71 has front power disc brakes. Can the disc brakes be used on the 69 from the 71 and if so, what do I have to remove/save from the donor? Is this an easy task or a lengthy project. Thank you in advance. Jason

The short answer is yes, you need the master cylinder, vacuum booster, combination valve, front spindles and everything attached to the spindles.
The disc setup from your donor car is the same setup that would've been factory installed on your 69 if it had been originally ordered with discs, so all the parts will swap-in relatively easy.

This is a pretty easy swap. The most important parts that you need from the donor car are the spindles and associated caliper hardware and the brake proportioning valve. The backing plates are nice but not really necessary. The disc brake booster should also be used in the swap.
Depending on condition you can reuse the master cylinder, rotors and calipers/pads or better yet buy new ones. The ball joints do not need to be changed.
How lengthy/difficult the project is really depends on your level of expertise. In my opinion not a difficult project.
I would say that the toughest part is separating the ball joints.
Also, the spindles are sided and I forget which is the correct way to mount them. In one orientation the caliper is at about the 2PM position and in the other about the 10AM position. In one of these orientations the flexible brake hoses do not reach.
