Mike Joslin 1968 Dart GTS

Mike Joslin, OH, 1968 Dart GTS, 426 HEMI, 5-Speed: This was our third Keisler 5-speed kit, and as usual, it worked flawlessly.  We got Keisler's new carbon fiber pistol grips, and the interior had an awesome look.  We drove this car from Ohio to Niagra Falls, NY, then to Mopar Fest in Canada and back.  It would not have been possible without Keisler's kit.
