Due to rushing to install the Z32 Nismo transmission mount. I didnt get to look at the exact dimentions. Unfortuantely the Z32 transmission mount is about 3/8" taller. Causing my driveshaft to click and stress out.

I will order a OEM one, and fill the gap with polyurethane mix.

I'll do that end of january.

Are you sure your old mount isn't just 3/8" collapsed? Mine was!

Nah, there was still 1/4" gap under the rubber to the mount bracket itself.

The 300zx one was just substatially taller. Even as I lowered the nismo/bracket combination, I could see the "flex disc" straighten out and the cracks dissapear. The cracks dissapeared once i lowered it about 2/3".

Im willing to ship it to someone else who wants to try it. But im ordering an OEM mount soon, so i'll have pics to compare the two.

Many times the center support, transmission support, engine mounts, and diff bushings are all sagged simultaneously. Even 1/8" off will create vibrations and stress.

Like new requires all new, then trimming the center support with zero or 1-2 thin washers to minimize the accurately measured vibration frequency and amplitude.

Trying to return a 100k car to as new is always expensive and time consumming.

One must use ACCURATE angle measuring devices to set the as loaded LEVEL sitting still drive line angle.
