I just brought home my first vintage and trying to understand its workings. Just first basic things first is locking her up! How!? Right now she has a locking core on the passenger side, but its just from the outside, no interior lock knobs (which i don't think they ever had anyways). The driver side doesn't have a core on the handle. Is there a way to lock these trucks up or was it just not a problem to leave the truck unlocked when you ran in to town back in '53? :-)

Thanks guys
