I have a set of Comp springs that might do what you are looking to do. They are 950-16, seat load 133lbs @1.900, open 332lbs @ 1.300, spring rate 333lbs/in, coil bind 1.200. I'm asking $75.00 + actual shipping, if you are interested, I'll get a shipping quote. PM me your info if you want a shipping quote.
