HotRodRocker if you still have the old spring and you have a compatent parts guy/gal. Have them pull out the illustrated buyers guide for there brake parts. This should have a detailed section on return springs with actuall size picture. You can then lay your spring out and see what is the closest match. Remember yours may be slightly longer because they have be stressed.
If you don't have a good Parts person take some photos of your springs next to a ruler and email them to me. I will pull out my copy of The Illustared buyers guide that I have from when I sold parts. Then I will email you the part number that I come up with. Good Luck
