Thanks GTA, yes the main reason is to avoid the annual reg. It just ticks me off if I decide to drive it maybe once a year I need to pay because the reg has expired. Happened last year, wife says lets go to dinner, can we take the little car? nope reg expired the previous September. It will also let me get collector insurance if I decide to go that route.
My understanding is I need a single period correct plate and can go that route and be legal, the weight is a new one on me but sounds simple enough to address. I didn't do the historic plate when I moved to WA because they couldn't figure out how not to charge me sales tax.
