When I first got my yellow car, the dog bone (engine torque strut) in it was in very bad shape, and the engine flopped around like a fish out of water. So I got a nice new polly bushing dog bone for it. But there was a problem with it. It is so stiff, that when you go from acceleration to deceleration, or vice versa, without pushing the clutch, the gears "bounce". Sometimes it could be pretty bad.
Recently I replaced it with one of Rodney's new rubber bushing dog bones...
Except that the picture shows a V6 dog bone (below an original), but you get the idea. The car rides much better now. So if you have a manual transmission car, and you need a new dog bone, I recommend Rodney's rubber bushing dog bone. For an automatic, it's not that important, and you can use either rubber or poly.
