Haha thanks for the offer…
I just got a call from Jason, the guy who runs Z31Performance and he gave me the low down on the mount and whats going on basicly, hes sending me a new mount, same design but thicker and made out of steel to replace the aluminum mount.
Hes also redesigned a new one in a cage type fashion like the stock mounts as a fail safe, so even if the acctual mount/contact points from the chassis to the back of the diff broke the diff has something to fall onto and keep it held up to prevent damage to the diff and rear end along with being able to limp it carefully if needed.
Anyways hes a nice guy not an engineer, it was whoever acctualy makes the mount, hes just the guy with the ideas and the funding to do it for our small community.
Anyways it was nice of him to call me instead of just throw me an e-mail
