when my brother was growing up, i had a bunch of tools come up missing. usually, some were found when "strange noises" came up for me to diagnose. funny how that works. one time, i found a 5/8" open/box wrench still attached to the upper starter bolt on my sister's 74 satelite [318]. come to find out it was left there when my bro changed the battery cable on the starter, stuffed it back in, then couldn't get the wrench off the bolt after tightening it. ah well, just leave it in there ........ no noises, so i didn't find that one until a couple years later when she had starter problems.
