Most guys here will vote for keeping the original color.
I lean that way myself.
Google "mopar lynch road fender tag decoding", and I think allpar.com has a chart.
From what I can tell - I'm no expert on Lynch Rd tags - it looks like:
VIN RM23H9A156698
SPD of Oct 28th
RR Hardtop, 383, 4speed, air grabber, hood stripes, tan bucket interior, T7 interior door color.
Some of the upper codes are #s for engine & trans as I recall, kinda redundant, but you might find the same #s written on a valve cover and stenciled on the trans case right side.
