Look back at the link I gave to that vacuum pump thread to see the equations you need - also please note different springs were fitted with different stiffnesses / rates for different chassis and engine weight combinations. You should ideally pick out a couple of springs that you think you might be able to find and then start from scratch with the measurements and length adjustments.

Stretch - aftermarket springs are available in known rates at varying lengths - 9.5, 10, 11 ,12, 13, 14 inches seem to be the most common. When I refer to using a 10" or 11" spring, I am not talking about cutting coils, I am talking about totally different pieces.
Behold!
An 11" 600 lb/in spring.
