If you decide to go down the resto way, before touching anything, get some tracing paper tape it on the frame, and trace the decals with a pencil, then measure everything up on the orig decal (overall and individual width+height of text and letters, line thickness etc...), just in case the guys in the other proctor thread cannot help through Cycle Logic. The more detailed you can trace them, the easier it will be to recreate them. For your luck, unlike with many fancy decals, these look like printed on white vinyl, which is a big pro if a budget recreation is to be done. But of course nothing beats a NOS leftover set.
