Something I've never seen or even heard of, a 1970 Bonneville that you can buils either as a convertible or an El Camino type pickup. The photo of the kit is in my camera which is in the truck, which is in the parking lot 4 floors below and I'm not going back down tonight. Maybe tomorrow.
I seem to remember the eBay listing said 66 Thunderbirds. I put the stanchions on my engine display stand but I can't get the "rope" to drape right. I'll have to try something else.Wow, that was an ordeal, it took three tries to get photobucket to uplaod it without jamming.
These are 1920's NY. Once you can find one side you can estimate the other. Also google the year you want. It will likely pop up as an eBay listing. Sometimes they give the size. http://www.worldlicenceplates.com/jpglps/US_NYXX_GI1.jpg
