Am I going to need to measure and have one cut/fit ? '72 Dart Swanger converted to 340, 727 and 8 3/4 (741). Seems like there'd be a stock length I'm looking for ?
Do a search there was a chart posted last month? with lengths of each car, then call/go to the salvage yard or have one made.
Just looked inn parts for sale there is one that may fit your needs.
