Hi Peter,

Just looking at your pics again. Are you using the Commodore rear cover and it's one central rubber mount? I would be a little concerned about the strength of the whole thing if that were the case. The Commodore uses 4 bolt positions on top in conjunction with the one rear mount. Just using 2 at the front and one at the rear might put undue strain on that one rear mount. You might want to look at using a Falcon back cover with 2 mounts or check the later Nissan rear covers as some of them may have the same rear cover bolt pattern (Some of them use the same gear sets as the Commodore).

Cheers
