72 Duster Resurrection

Thats a screaming good deal on an A body disc setup. Local too. A 74 duster is still an A body like yours His upper control arms are the big ball joint ones. Thats what you use with those disc spindles with no adaptor sleeves. You will need a ball joint for the one upper control arm thats painted. Its a K772 joint. As well as bushings for it. Might as well rebuild both of them with new joints and bushings if your going to use them. Or you can use the small ball joint ones on your car with the adaptor sleeves

The lower control arms are the same part from 1962 to 1976. Only difference is some have tabs welded on them for swaybars. The ones on your car will work for this swap.

You will need the A body disc brake hoses from 74 to 76, disc brake proportioning valve for A body from 74 to 76, and the manual brake A body disc brake master cylinder from 74 to 76, and ten 1/2" RH lug nuts since the pic shows there arent any.

If you decide to use your small joint arms with the doctor diff adaptor sleeves, and original lower control arms, you can sell the big joint arms, and those nice painted lower control arms and recoup some of your money. Id look on fabo sales and see what the going rate is on those pieces before selling them, as well as selling all the front drum brake stuff.

The bonus is the big bolt pattern 14" wheels. And extra parts that come with it. Typically just the brake setup from the spindle out, with no extras like rims and suspension arms goes for $250-$300. You will notice the disc brakes come with way bigger studs 1/2" instead on the 7/16" ones on your drums.

If you buy this setup, and i recommend you do since its local, and you can recoup your money on the extras you dont need, unless you want to wait and come out this way for a set of cheaper M body brakes (same thing except for larger piston caliper, slightly changed spindle) you can prob go 2 ways.

1 sink a bunch of money in the disc brake setup right away and swap it in,

2 do a quickie fix on the drum setup with minimal money spent just so you can get the car up and running, and round up all the parts including new upper and lower ball joints, pads, master cylinder etc and rebuild the disc brakes as time and money allow and get it all ready, so you can do the disc swap in a weekend.
