they fixed it but thats not the point
they made a custom driveshaft and didn't even balance it at all the first time
I havn't needed any driveshaft work for awhile I will be if columbus joint and clutch went under
I like columbus joint and clutch they get it right the first time....
ask derek about the sweet balance job driveline one did on the driveshaft for his rx-7
summit stocks a header for it....
