[LO23]

Quick question to those of you with a title to your LO23 (or anybody else who may have the answer)-


Should the title read "LO23" or "L023" (as in L-zero-23)? My VIN tag looks more like a L-zero, but obviously people tend to call these cars "El-Oh-23" darts... and yes I've heard that Os were used instead of 0s because zero wasn't supposed to be part of a VIN in the olden days. But what should the TITLE read?? Thanks in advance for any help!
