Is anyone running a 1 piece driveshaft in their burb? I had one made back in the 90's, but it seemed to vibrate more than the 2 piece, even with new U-joints. I have some literature from GM on the '65 Chevy trucks, and it says that the 'burbs all had 2 piece shafts but the pickups only had a 1 piece. Is there a reason for this. I'm wondering if I should take my 1 piece to an actual driveline specialist and have it checked, as it has regular washers as weights on it, and it was done by a muffler/ driveline shop.
