Coilover spring rate.

[Badart]

I am currently building a 74 Duster Pro street car and I am wondering what coilover spring rate I should have in the rear. It will be used mostly on the street for cruise nights and around town driving. 440, 727 combo. I am installing a chris alston prostreet 4 link. The car will not have a cage and will have a back seat. The tubs are installed and I am running 325/60/15 drag radials. Thanks for the input.
