large drum brake kits for 60's - 70's Fords

[TS69GT500]

Has anyone installed one of the large rear drum brake kits as offered by Ford Racing and others on their classic fords with power brakes?  11 in x 2.25
I know most kits only fit the late model large bearing flange although I think some are offered to fit small bearing housings.
I assume the wheel cylinders are either 1 in or 1x1/8 and the master cyl must be matched to provide increased volume.

If anyone has done this upgrade what master cyl did you use and was a "residual valve" required?
Basically, was this a simple swap parts upgrade?

Thanks,
TonyS

I miss the trips to “Pick Your Part” auto salvage back in the 70’s and 80’s searching for neat stuff to use on my   my street car or race car. One particular trip we found the large drum brakes from a station wagon (I think in that size) and they were basically a bolt on to my 9” rear end. Used the original mustang power brake master cylinder and they worked just fine.
