Stop in for a cup of coffee

Good morning everyone!!! So I have seen this question asked but I dont know if I have ever really saw an answer so I'm going to ask. What is the driveshaft length for a Duster with a 727 and 8.75 rearend. I had one cut down here a while back for my son's car but, I think (judging from the vibration) it's too short. I just measured the one that was in the car when I had the one cut down but, not sure what it came out of..


We measure the length needed by jacking up the axle (Keeping the springs with load on them) and putting the slip yoke in the trans... Then measure from the center of the slip yoke u-joint to the center of the axle u-joint and then subtract an inch for installation...
