I think that VIN and tag from a 72 W30 would definitely be worth saving with the X in the VIN denoting W30. Previous years don't do that, as you know.
That VIN plate from the 69 Hurst is quite valuable as there is a listing of all the VINs of the 69 Hursts that was found at Demmer. Would be interesting to peel back the floor or trunk floor in the area of the frame stamps and compare that number to the listing..............or not.......
