Mine is not for my 70' Challenger but from my 70' Charger I have had since & I was a teenager. It has a 440 Sixpack, It's an R/T, & has the S.E. package. Hence the 6PKRTSE.
In 1997 my daily driver was a BMW m3...BMW's "Ultimate Driving Machine". Since I tracked it at the Glen, I plated it DRIVUN. Same car and same plate in NY, Ontario CA, California and now Georgia. Challenger plate is 4DRYVIN as its headed to Power Tour.
