Decooney Hi Duane I would put a limiter bar on the motor and stay with the rubber mounts. The other trick is to put 2 bolts through the mount and bolt it snug with aircraft hardware. You need a little movement or the solid vibration could cause cracking in the frame of body. I know it's a cobra, BIG and LOUD but some race parts are not the best for an application like this. Match all 3 mounts for the same limit of travel. I had a set of these in my jeep in 85 when they first came out and snapped one 4 wheeling. Life time warranity. I put flat shoulder bolt through and never had the problem again. Mount the limiter bar to the bell housing bolt and not the front of the motor, otherwise it will twist when rotating. Trail and error learning. How the 4 link coming? Have a good day Rick Lake ps 20F outside and 4 inches of snow and more coming.
