Does anyone know how to properly measure ride height, and what are the factory specs. I wan to upgrade mine, but don't want it to heigh or low.

Well, it's kinda complicated to explain but quite easy to understand if ya got an Assembly Instruction Manual (AIM). For example, on a '68, UPC 0, sheet A11, it tells exactly where to measure from and then the following pages gives the specs depending on what options are on the particular car.
