I bought it, but don't have time to pick it up, so had them ship it. My old stock driveshaft vibrated, even after having it balanced, and I just replaced the 8-3/4 rear with a Strange S60 with a spool, and the 1350 moly yoke from strange, so I needed a new driveshaft that was shorter, with 1350 U-Joints, and hope it does not vibrate.
