When we moved to Washington State from California, all of the parts for my 1969 BOSS 302 were bagged and tagged, and in boxes carefully placed on pallet rack shelving. However 1,200 miles later and with movers placing items that started in the garage in the library and items that started out in the guest room in the garage. Well, I couldn't find a darn thing especially as parts were put into a storage unit, then forgetting what was packed in which box. 10 years later with a 1970 BOSS 302 added to the group along with the associated parts that arrived with it. Well, I couldn't find a darn thing.
Covid-19 hits and my daughter was home from school and my job was furloughed leaving the both of us with a ton of time on our hands. We started an inventory, culminating in a spreadsheet with everything listed (well almost everything, we keep finding things I forgot we had) by part number, item name, and quantity with where in the heck the parts are.
I would suggest going beyond bag and tag, the spreadsheet is searchable and location makes the job of finding something take minutes, instead of days. The better your inventory process, the easier eveiis accomplished.
