I have two very old medium size suitcases, blue one holds all my trans to carb cables and trans mounts, all the information I run copies of for trans to carb parts, my old gray one holds all the information and parts for my engine bay, pullies, alternator mounts and even alternative mounts . If anything happens to me my two sons will not be in the dark, but yes, buy a couple old suitcases from a flea market or grab a couple from old friends, they work great and most have a place for paper work.
