Does anyone know where to get poly motor mounts for an 86 Maxima?

 

You can't.

You must poly fill them instead.

 

I did this on one of my fourth gens. I ordered either shore 80 or 90 from McMaster Carr, everything is holding up fine and it has been about a year. I did let them set up for about a week before I put them back on the car. I had the engine out of the car so I was in no hurry to get them back in. If you do go this route I would suggest that you get an extra set from the junk yard and fill those so you will not have much down time with your car.

 

so the polyurethane or simmilar material can be purchased from an auto parts store? I seen a cardomain on someone who's done this but I can't remember who it was.
