Unfortunately those that Mick referred too are either on the large or small side, they're sized for Cali plates, and the bolt hole spacing is wrong for the vintage Wa. plate. One of the vintage plate dealers sells one he has milled from aluminum with rounded corners/edges. He sells them in brushed finish, but with some smoothing and polishing you can make them look almost like chrome. Also, none of the vintage ones I've seen are lighted, you'll have to improvise with either a Hollywood accessory type, or lightning bolts (l.e.d.s in an acornish bolt head). The Early Bird swap at Puyallup is Feb 14-15, Jim (the plate dealer) is usually there. He gets $35 ea last I saw. Just looked on Craigslist since he often advertises there. Looks like he has another style available too, his number is in the ad; http://seattle.craigslist.org/see/pts/996620639.html
