My kit was delivered in 1994 and believe it or not, I still have the boxes. I think I may be the only builder that bought the complete Classic 4 kit with the 503 engine. The factory had just discontinued the XL and I think they put all the leftover XL parts in my crate along with all the classic 4 parts.
Anyhow, there were duplicates of lots of rivets, camlocks, rod ends and such. I kept the boxes and whenever I buy parts, especially buy something that won't be used until I do the condition inspection, it goes in the proper box. Also old hardware like wing strut and landing gear bolts and nuts goes in a sandwich bag labeled "Used strut attach", etc. and then into the part box.
I can find anything I need later in just a minute.
