Ya… local shop was an hour away and they did a great job and did exactly what I wanted… however… I was wrong… and that’s where we are now, and chasing a driveline vibration when everything is new/rebuilt from flex plate to rear tire… and the vibration was there before I started this project. So this time I just opted to include no part of the old driveshaft or slip yoke, and start fresh with correct measurements for correct length, and see what that got me.
