Upgraded poly bushing kit for the upper engine steady rod or "dog bone". These poly bushes last much longer than the rubber bushings and aid in keeping the engine more stable. This kit uses sleeves for 5/16 bolts rather than the lower which uses 3/8 sleeves, but bushings are otherwise interchangable. This kit can be used on all upper steadies from 1962on. 
 
Comes as a set of 4 bush halves and 2 sleeves.
