Moving Rear End Back 1"

B body SS Spring perches move the eye position back 2" from the std B location. that would be too much unless you drilled a 1" back hole

That's what I figured the OP could do. I matched up the hangers again with the stock A body ones and the difference in spacing is only about 1/8 in total on two of the studs. Just drill out two mounting holes on the car a bit and should go right on.
