82-83 Torque Arm Mount Bushing
 

I need a new tailshaft mounted torque arm bushing for my 83. It appears that the the 82 and 83 are different than the rest of the year models other than the later year torque arms have the lips either facing inward or outward.

Has anybody had luck in finding a bushing that will fit the 82-83? Is there that much of difference where the later year applications couldn't be modified to fit?
