I have tried the searches and as yet can't find the location of the Rear ABC valve block and accumulator.
For the love of god, some one please tell me how to access the dam thing

Yes thanks I have seen that. It does not tell me anything regarding how to locate the block, just the general area on a diagram. For example, looking at that diagram, the pressure reservoir (actuator) #4 looks like its behind the seat.....some how.
I know and have seen that the front valve block is located under the L/H front fender protectors, so that tells me exactly. How is the rear block accessed? Is it under the seats or under a cover under the car, or even in some sort of tunnel under the car? There are plenty of photos of the front block and actuator location but not the rear unit, are there any photos of its mount?
And thanks for taking the time to post that.

Remove the plastic catch panels off the bottom of the car. You will see it located to the left middle rear side.

The rear accumulator is item 4 in the diagram and can be found towards the right rear underside of the vehicle.

Next to the rear valve block is a small air cell called a return reservoir.

There is a pressure accumulator on the front valve block.

The rear valve block is under the splash gaurd on the left rear just in front of the wheel.You can't mis it. Also you can have them rebuilt for $100. There is a shop you can send to and they turn around pretty quick.
