Sorry for taking so long to get back to this. There were 3 main types of plate. Season 1 'HAZZARD', Season 2-5 'HAZZARD COUNTY', & the green 1983 plate from S. 6&7.
There were a few variants for nearby counties and at least one 'Atlanta' plate.
Most all of the S1-S5 plates had the 76. All of the metal ones had slight variations from one to the next, because the graphics were all die-cut and applied by hand. Earl Hays still uses the same method to make plates for TV or movies even today. The graphics were made of a thick cardstock type of material in whatever colors they needed. I think they use a spray adhesive to attach them. They seal the finished plates with a really durable clear coat. If the graphics for a plate are too complex for die-cut pieces, (like something with a color fade or a really busy design) they will color print those portions of the design onto a clear vinyl sticker material and put that on the plate. The actual plate number is always a die-cut graphic so that it has extra thickness to look raised like a real stamped plate. Their metal plates also always have a raised/embossed border and it's the only embossed area on the prop. For California prop plates, sometimes they will flip them and use the opposite side of the plate because real Cal. plates have a border that is sunken in or debossed.
There were a lot of plates that were made from 'Crescent' brand mat board, the same stuff you'd use for a mat border in a picture or poster frame. Most of the time they would use these for background vehicles, but every car had at least one of these at some point. They liked to use these for jump cars because they were cheaper to replace. (I think the metal ones were about $25 a pair back then. Now they cost $80.) The mat-board blanks are machine-cut by EHP from the sheets of mat board. They would then use a lithograph process to print the graphics on them. When they were present, both metal and mat-board plates used the same type of registration decal stickers. The metal plates sometimes (but not always) will have these clear-coated over along with the rest of the plate.
CGLFC has been gone at least a couple of years. It was really active about 10 years back but interest in the page just sort of faded out sometime around 2011-2012 and people stopped posting as regularly. I never understood why, but the page was a really great resource for fans in the time it was active.
I can ship anywhere, it just costs me more to send to Europe so I'd have to calculate the actual cost.
I think someone in the WB prop department threw the Reunion plates together at the last minute. They were vacuformed plastic and have no detail at all. The second reunion had better detailed plates. I've got a file for those 2nd reunion plates saved and can make them as well.
The red part on the front that looks like a plate is actually an optional part for a 1969 Charger. It's the attachment bracket (don't know the official name for it) for a front license plate. Most U.S. states don't use front plates, so a lot of Chargers don't have this part. Most of the time the car builders for Dukes would just spray it orange along with the rest of the car, and didn't really take the time to remove them.
