[Roadsters] rear brake cylinders

I'm not a racer, so I don't know how much effect putting the 3/4 wheel 
cylinders may have on overall brake performance.  I.e., will it improve 
baking overall? Nissan must have had a reason for increasing the size of the 
rear wheel cylinders with the '67-1/2 cars.

I've never found the brakes on my '66 with 11/16 cylinders to be wanting, as 
long as I stand on them hard enough.
