My recently acquired KDI-17 does not have door springs. Can I just buy some dishwasher door springs on eBay that appear to be correct (part #4160097 looks visually close to me), or do I really need to try to find the model-correct KDI-17 springs? Same exact question about the leveling feet, as I am missing two of the feet. I was considering taking the feet to the hardware store and just buying some bolts that match the diameter and thread pattern.
