1964 plymouth valiant 4 door to 2 door conversion

Hank,
I did it about ten years ago. It is not that hard nor expensive to do if you have a good 4 door car and a two door parts car. I bought a two door parts car for $75 and took of the doors and carefully cut out the fronts of the quarter panels and took off the roof for extra sheetmetal. The car is still on the road somewhere as I had to sell it when I got divorced. I put frame connectors on for stability, too. Do it and good luck with it.
