I talked with Bob G and he has the decals. According to him, early seat belts have the Kangol decal (it doesn't have a kangaroo like I stated earlier and I don't know how I dreamed that up) and after '69 the buckles have the star on them. However, Bob knows a whole lot more about that than I do. My '68 belts are defintely original and have the Kangol decal.
Thanks for all of the input. I am glad I found the decals!
