FINALLY!!! found a good used transmission; looks to have been recently rebuilt, to put in the Dart. Came out of a 70 model Swinger 340 car, so there should not be any problems with installation. I'm going to still pursue having the trans. I originally put in the Dart rebuilt so I can keep an extra one just in case.
Finished up the interior.....installed the seat back release levers and bezels, as well as the seat track cable that runs the width of the seat connecting the release arms on the bench seat tracks, so the seat will slide forward and backward evenly. Only thing I'm lacking is the seat belts which will be in the end of the week and a good cleaning and waxing, and a front end alignment! Ben.
