Rear Springs

I replaced the front springs on my P6 and now my camber issue has cleared up,the old ones were 16” long when they were out,so quite a bit shorter than new.
I need to replace the rears as they have sagged quite a lot I might have a line on some here in Vancouver but in case I don’t I might have to get the old ones reset,but the WM doesn’t give you the spring rate,does anyone know what it should be?

I have a SET of OEM front and rear springs I can check free lengths on if anyone is interested. Taken from 3500 auto 1972.
