rear engine mount ?

Who's mounts have you used, and were you happy with them ?

A lot in the forum archives on this subject, here is a search string to get you started:

Here is a thread I started while sorting out the mounts on my P15:

In answer to your second question......many of us are not happy with the mounts currently available.

Thanks Sam. My car is a 40 K survivor, with little to nothing done to the engine or trans. It does not have the lower insulators just a thin rubber washer and a steel washer under the drivers side and only a steel washer under the right side. After reading a bunch of posts during a trans mount search here, it became kind of apparent that the lower mounts are missing from many of the cars and situations I read about, leading me to believe the lower mounts were not used in most cases. I believe Mopar fooled us a little with the lower bushings. I don't think they were used as widely as depicted in the service manual.

 

Anyway - I bought a pair of those Marmon motor mounts from rock auto a while back - the rubber seems soft enough but what concerns me is they appear to be taller than the originals. I found during a search another member here had measured the height of some nos mounts and that measurement was 1.22 inches. The marmon mounts are 1.40 tall. Would you think using taller rear mounts would pose an issue with driveshaft inclination, enough to be worried about?

That is only a difference of 0.18", about 3/16", I don't think that will be any reason to worry about the drive shaft. However, you will most likely need to adjust the shift linkage after installing the new mounts but that is an easy procedure, just follow the service manual.

 

The lower mounts are still a mystery to me, I've never been able to figure out what the original config was on my car. It only had the washers on the bottom when I got it but I installed lower mounts in an attempt to reduce clutch chatter. But the lower mounts do transmit a bit of engine vibration. Be prepared to experiment some and use what works best for you.

Your "missing" lower mounts are not missing, that is stock.  In the downloads section I posted the TSB that explains this exact setup.
