I've just got done building my second 372 in a year. At this point I've got a bunch of parts laying around from collecting and the 375K's that I've used to build them. The question I have is how much do you keep around spare? Most of these parts are already allocated as I don't think I'll ever wear either of these out and if I do... I'll get more parts. Storage is a problem at my current location but I got to wondering... how much do you keep and how do you sort it?
