Keith, Some years ago, I had a similar problem with a drive shaft shop. I had a another cast iron TorqueFlite transmission on hand, so I removed the flanged part that drives the shaft through the hand brake, removed the hand-brake drum and took the assembly to the drive shaft shop. They then had no problem balancing the driveshaft with the ball and trunion. unit. Hope this solves your problem. Gary Hagy 300-C conv. In a message dated 8/18/2011 3:25:14 P.M.

Says he warned me and it's my problem to deal with. Keith - On 8/18/2011 5:17 PM, sirvanhool@xxxxxxxxxxx wrote: > That person is a nut.
