I learned a lot time ago to not stockpile any parts unless I know for absolute sure that they will fit. I've fallen outside of the return period on some fairly expensive parts by doing that and wound up having to sell them at a markdown.
Thanks for sharing that, that’s a really import ant point to keep in mind… the “other” more unpleasant side of procrastination… maybe I got lucky this time with some grace… but yes very good point, avoid stockpiling. Thanks!
