Thanks for the tip Jerry. Just out of curiosity I called the dealer and they only sell the whole "cup" assembly, not just the spring. I stretched out what was left of the original spring and it seems to be holding up fine. I will take the remainder to the hardware store to find a close-enough-for-me replacement. Just glad it is all figured out finally! Now it is onto fabricating a guard for the hydraulic filter......much more fun than buying one!!!
