1/4-elliptical spring specs

Listers

I want to have my 1/4-elliptic springs checked while I have them off the car
(my spring boxes are being repaired).  What specs do I need to provide to a
spring shop?  (I've located an old posting of Frank's with the specs for
semi-elliptic springs but I can't find 1/4-elliptic specs).

Thanks for your help.
