Does anyone have the correct factory "free arch" dimension for 1969 Z28 4 leaf springs? I emailed eaton Springs with this question with no response. Thanks,
Gary

No, but the factory manual has ride height dimensions for the rear. I think it is a measurement from diff housing axle tube to bottom of frame rail arch or to the bumpstops.
I don't have a 69 manual to look it up for you though.

Thanks David. The Assembly Manual shows from ground to bottom of rocker. I called Eaton and the said 5 3/8" of free arch.
