It depends... The Buick parts catalog lists five part numbers for the "standard" rear suspension, and five more for the F40, F41, FE2 and FE3. I suspect there was overlap, but still, it was way more than just one spring rate. The Moog part Turbo6inky gave is probalby a "middle" rate, but GM catalog doesn't list rates. Well, Buick catalog doesn't, other GM catalog may..
