New front Poly motor mount Yes, it's homemade - but stout !!
I'm still waiting for prototypes of drop in replacement poly mounts, but needed to do something because my front mount was shot....
Some searching turned up Energy Suspension 4.1104G Transmission Mount with "close" to the right bolt spacing. Just need the stock mount base and a piece of 3/16 x 2" steel.
Pics should say the rest...

Compare stock vs new poly setup...
The stock mount compresses 1/4 - 3/8" when installed - so although they line up even unloaded, the poly will not compress the same. I did not use the second steel sleeve as it made installed height to high because the poly does not compress.

Now the install - the mount was out for opening the bolt holes. The easiest process is to bolt the poly mount to the bracket and install, then place the bottom piece in cradle slots, then bolt lower bracket to mount, then lower engine and tighter lower mount to cradle.
Special note - due to thickness of stock mount bracket, the bolts that comes with the poly mount are not long enough - you'll need two 7/16-14 x 1" bolts.

Niiiiiice.
This is awesome to see another angle on a common problem. I had to re work mine shorter than stock as well plus its good to have a little preload with the motor tilted foward . I had to redrill my dogbone and decided the dogbone should be used I didn't want the cradle and/or block mounts to crack or be under to much stress. Mine survived the first track passes. Well see in the future lol.

Thanks X11 Nut for the mount. Great finished product and a professional, clean design. Just comparing the two mounts side by side in person, one can see how "squishy" the stock mount is compared to this. I installed my mount a few days ago and today did some hard pulls and normal driving around town. Mount feels solid, no additional vibration, and although my car already shifts quick/hard due to the Cartuning trans build/tuning, this mount is definitely one of the missing links I needed for my set up to help get the power to the ground and make the mounting points more solid. Good work!
