When I said be sure it all matches up I meant do it legally. Regarding the altering numbers gig I think freestyle 111 is right. A buddy years ago was into street rods. Often when modding to a late model front suspension or restoring the old Fords the frame numbers would be cut off as an unused part of the old frame. He showed me a custom stamp he had gotten from an old Ford restorer that had a unique shape for the number 9. It matched the font of the origional Ford stamp.
