Looking for info on Ron gable #18 67 dodge dart that raced Trans am

Here's a small story on Ron Grable's '67 Dodge Dart. In '67, it was not a common thing for cars to have a full roll cage and one where the seat was connected to the cage. Ron was ahead of the curve in that regard. He was not far enough ahead to incorporate a fuel cell, however. Ron and Bob Tulliuswere the only two in the nation making a serious try with Chrysler products in '67. Chrysler pulled out of direct corporate involvement in Trans-Am after '66 and did not return until the '70 season.
