This is a great unit to replace a Bendix Treadle-vac. Master Power Brakes has this replacement in stock.

Universal 7" single diaphragm power booster with 1" bore master cylinder for disc/drum applications. No mounting brackets. Vacuum hose kit included.
Retail Price: $195.00 (New,not rebuilt)

You will need to make an adapter plate in order for this to work.
The Brake booster/Master cylinder combo, will work with drum/drum brake. Use a I" bore for this application.
You may also need additional items such as residual valves and adjust brake pedal ratio.
Of course there are other options you can explore as well.

I'm going to try a late model Crown Vic unit. There are a few good ones in a local yard and they look and mount similar to the one pictured.

Might be a low cost alternative. (adaption required)

That will work on some models .... However on cars like my 1959 Lincoln. I have 4 wheel drums ......So the fluid reservoirs need to be the same in size and or volume. Additionally there is no proportioning valve ...... nor is their a residual valve.
The residual valve will cause the brakes to drag.
On such a massive beast I would be happy to just stop.! Keep in mind the above unit pictured is designed for use with drum brakes....
There is a guy that used the above setup with much success, No proportioning valve and no residual valve on a 1960 Lincoln.
On the original set-up the one master operated all four drums at once. I do believe an adjustable proportioning valve would be best.

They don't list a master/booster specifically for a '58 to '60 Lincoln with 4 wheel drum.

The pic you posted looks like their model 1501 universal for disc drum.

Another source for that assembly is Speedway Motors. http://www.speedwaymotors.com/Single-Di ... ,1983.html

The crown Vic unit doesn't have a built in proportioning valve, none do, and with a 10psi residual valve for the front it should work just fine.

We'll see

Hmmm.... 1" bore is quite a lot larger than original .62" bore. I bought a retrofit 7/8 m/c from an 88 buick regal which also has the resivour angled to exactly match the angle from the firewall to horizon, and without the large vacuum resivour connected its a bit sketchy. This is with an aftermarket dual diaphragm booster which is miles more boost than stock, and more than similar single diaphragm units.
