Quick Lift

My question has to do with where you placed the rear blocks? I have a '67 Dart convertible and the QJ blocks don't line up with the frame members precisely as the QJ ramps are ever so slightly shorter than the front/rear frame rails. I see the 'Cuda has the front rails on, but no pics for where the rear of the car sits on the QJ. Thanks!

Darts 111" wheelbase?
I'm out as far I could go on the cuda. This car has a 2" X 3" tie in. I don't have the car on it right now but the rubber block is 3-4" in front of the spring eye best I can guesstimate from this picture.
