Just took a look at my original and later printing 1971 parts book and there is nothing listed, at least not under suspension parts. After beating my old noggin on the wall for a couple hours I do remember something about traction helpers or something like that, but those brain cells are pretty much toast. What is the SPD of the car?

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
