75 Scamp suggestions

Get it going is the first step.

I had a '76 Scamp, I made it look a lot better by changing the markers to '71 style and then sinking in the bumpers. Get rid of the bumper guards to.

If you can find a '73 or '74 Duster/Valiant/Scamp, you might like the grille even better.
If you use the grille, get the grille support and headlight bezels to because they are different.

I would like to have another Scamp. One that does not have as much bondo in it as the one I had.

Cutting out the metal and replacing it is the only way to go. Fiberglass is only a band aid as it will generally rust out around the area that was glassed.
