73 Dart Swinger Vibes and Solution?

Thanks, Yes the car is on stands. I have returned the DS to the Ohio Driveline Shop and splained the issues. It has very little use, so they will re-spin and check the balance and go from there. They did confirm it's about 1/2 inch under optimum measuring center to center. I see that on the old worksheet they had me measure from the output shaft to rear center. That's why I did not remember indexing the yoke on the tranny when ordering initially. Maybe they will cut me a deal to make it exactly right!
