Have you contacted MOOG and asked them what they replaced it with ? Many times they change something a little and give it a new part number. It may be superceded.

Have you thought of contacting Eaton Spring? Perhaps they have the specs for the Moog spring, have a better option, or can make what you want:dunno:
