I'm replacing the torque arm bushings and transmission mount on my j-20 with new poly ones. My problem is that the raised part of the torque arm bushings prevent them from clamping tight to the torque arm. There is about 1/8" of space between the bushings and the arm. Is this the way it's supposed to fit? If not, what is the fix for this? Shop book isn't much help. Previous owner used a long 1/2" bolt and a bunch of flat washers.

Thanks, Dale
