so in the case of my '72 vette, the deeper/forward section goes to the Y mounted toward the rear of the car, and splits to each side.....

same Y for the front, off the first activated piston, as mounted it's toward the rear of the car in it's location, in the housing.....

OK, I get this. Thanks.

Now I have to go back and re-read the rest of what you wrote, and think about it some more!
