I've never seen any, but Tom and myself have discussed this before. we were talkng about what it would take to make the '58 (available in varying scales) appear to be a '59 by smoothing the louvers on the hood and removing the trunk spears. I don't see why that same thing can't be done say with a '63 to make it appear to be a '64. The gill issue on the later years would pose a problem though.
If I see any scale models, I'll be sure to pass it on here.
