Stop in for a cup of coffee
I have a 72 dart that was an original 3 speed A 230 with 8.75. When I put a 4 speed in it, I kept the same driveshaft only changed the yoke on the front for the 30 spline output on the 4 speed.
When I swapped a 4 speed into a charger, I also used the same driveshaft and yoke.. a 727 and B/E 4 speed are the same length.
This duster is the first time a driveshaft has stopped me like this one.
