Speedway has a guide that says a ~1800lb front end should use 425lb springs: https://www.speedwaymotors.com/Mustang-II-Suspension-Front-Springs,45731.html
Not sure if that is 100% right for your application, but if you run the numbers and come up with something in that ballpark, it is probably correct.
They also say the standard length is 13.5".
Eaton sell a whole variety of lengths.
I see a number of places that list 8.5"+/- as the correct compressed height with the lower control arm parallel to the ground, so that gives a ballpark of 5" of compression.
