It's an 8" dual booster.

I have no issue giving up the treadle-vac feel for a modern booster and dual circuit master. It's my top priority before I even buy new tires.
Thanks,

Very interesting and sure would like to know more when you find out. You said ABS Power brake makes it but I didn't see it on their website. Is it brand new and only shown in car specific listings or has it been out for a while?

The dual 8" surprises me because if the toe board is the same size and shape as the original, it looks to be mounted close to the same height vertically but maybe moved to the right a few inches. In the stock location a 7" diameter booster will barely fit the space without hitting the frame and a dual 7 will barely make it without the end of the master hitting the steering box. To have a dual 8 fit they have moved it upward and toward the steering column a bit to clear both items. Am wondering how close that would put it to the torsion bars in a 55-6 model and how much clearance to the air vent tube. If both those items would be clear it might even work for 55-6 models with factory AC. The blower position on those cars has been a big issue when trying to make anything that has been done so far work.
