Anyone know if the rear two isolator mounts are usable-interchangable for the front engine mounts. The only difference by eye i could see between them was the rear ones have a diff. Thread on one side which screws into motor case. I could care less about that. My front lower isolator bolt delaminated from the rubber puck. I have extra good rear isolators from a spare 98 bottom end. Just want to swap 1 to front.

 

One part number difference between the two mounts probably because of the thread pitch difference if there is any. Not sure but think the rear mounts are a tad thinner than the front isolator mounts,but don't think that would cause that much concern..I'd go for it rather than wait for one. Just make sure you have a nut that will fit the bottom threads if the thread pitch is different.

 

Yes you are right the rear isolator mounts are a tad thinner, only about 25-30 thou. I'll just make that up with a washer on bottom. Thanks!
