AOD valve body springs

a friend is rebuilding the aod trans in a marquis and when he dropped the valve body he found a broken spring. my question does someone sell just these springs for the valve body?
any help would be greatly appreciated.

Anyone rebuilding an AOD tranny will find these tech articles from lincolnsonline great reading. The first link under "general transmission" has a list of suppliers links at the end of the article. http://www.lincolnsonline.com/tech.html
