motor mounts ?

[fishy68]

I tried a set of Poly locs on my mild 408 and it destroyed the drivers side in 2 yrs. of mostly street driving. I now have solid mounts on it and have NO vibration issues. If you have a vibration issue your engine (or an accessory) is not properly balanced

Have an unused torque strap still in the box, if interested.
