little info i found
Charlie Allen's car was "updated" all the way to 1972 (to look like the current model year) and by the late 80s was owned by Roland Osborne and Crhysler Power Magazine. VIN said 383 and I don't recall the fenderwells being cut out. I have pictures of the car at home.
the kohr's in P.A. have the car now I believe.
