How much interest is there in a Demon registry?

I don't think originality is what he is after he just wants to document all demons. I know where there are a few in a junkyard and I will be providing the vin and fender tag info for them. As well as a bunch of dusters and dart sports from the same area.

See if you can buy one of those Demon VIN tags for me if one of the cars is a 1971. Then I could get a tag for my drag Demon and drive it to the track (5 back country miles).
