That rear dose have the large yoke does it?Over the years lots of things get changed.Like said look at the joint in the shaft.You should see 2 clips on the inside part.Two also go on the 2 ends at the rear and also like said check that the straps are for the small joint.I think somethin should at least be bent even if the caps flew off.Double check everything.Was the rear and straps in the car before and was anything changed other than the joint?Rocky
