Denny:
Take some comfort in the fact that you are not alone in this situation. My shop walls are completely covered with the many parts that are "waiting". I have purchased 3 of those plastic drawer modules for the smaller parts which are rapidly approaching full. Besides waiting for parts there are those being prepared for the 1 hour drive to the brother-in-law's for weld repairs, those waiting for warmer weather, those waiting for budget / funding, those waiting for ordered items, and those set aside waiting till I get into the correct state of mind to tackle them.
In the end it's the work that I enjoy and I don't mind having lots of parts "hanging around" I just hope my storage system works and they can all be found when I'm ready
