73' B3 340 Duster pro touring build

I just discovered my 32K original mile '73 Olds Cutlass Supreme has developed a bad case of rust on the passenger side rear wheel well (unknown to me as it was in storage). After the initial shock and the disappointing fact that re-pop panels are not available for this specific car I was devastated. After a consultation with the best body guy in the area and him telling me that he can't even get it in until March, my initial thought was......."This clown better be as good as 76orangewagon." Enough about my troubles! UPDATE! UPDATE! UPDATE!
