OK. I have added the stock F block and R 3+2 block to the back of my TC3, and took pics to show what i was talking about a few pages back. Measuring the rear hinge pin shows me a difference from the front of the hinge pin at .375, and the rear of the same pin at .385. This gives you anti-dive in the rear of the car. It is a slight amount, but this is why i mentioned you may need washers to make sure you have zero squat in the rear. These measurements were equal on both sides of the rear of the car.

This pic shows use of no washers and the mounts used...
