1969 Plymouth Valiant 2 door

Frank en Valiant has a lot of potential. The Quarter panel metal has been seriously abused and stretched by the magician bodyman that performed the masterful dent removal sometime in the past.

I am looking for a quarter panel from a 67-69 Valiant or at least the section(even from a 4 door rear door) that I could replace it with.

Working on a tight budget(are'nt a lot of us) so I would like a trade or reasonably priced part here...it is going to be a fun driving car, not a $50000 hemi tribute car...
