Well had a play about with the diff mounting today and managed to fit a welded frame to the nose of the diff and two rubber mounts.
Bit of a tight fit but it all goes in....just.....
Also fitted the spreader plate to one side of my diff bolted to my chassis bracket.
Obviously the spreader plate is in line with the bush and the spreader is at an angle to the diff housing. Does anybody know if this is the case on the MX5 or is the chassis mounting at an angle to run in line with the diff housing.
