Vibration

C9ZX, I thought about that. That's why before I got it down from the jack stands, I went all over that car from front to back with a mechanic stethoscope. I mean everything. From idle to 5,000 rpm from 5 mph to at least 80 mph. I swear I was under that car for 2 hrs with that rod. Nothing, not one vibration. I just wish I tried it on the poly mount. I picked up the stethoscope after I changed the mount.

Thing is I also forgot to mention that the ploy mount was almost a 1/4 inch taller than the old style mount. So I think the pinion angle being off a little and the hardness of the poly mount was it. Well it is gone, I put about 50 miles on it today and nothing.

I wanted to tell you this summer, I put in a poly transmission mount and I though my 73 was going to fly apart.

I changed it out for a standard rubber mount and all viberations left.
