Rear engine mount

The rear mount will be a lot easier than the fronts. It's basically taking the place of an existing bracket that bolts to the bottom of the gearshift mount. A plate will be made that does the same thing, but instead of mating with metal, it'll go via a Landrover rubber mount that I've bought.

This is the existing bracket in place;

The two bolts at the top will be reused, the one at the bottom will not as it was actually hitting the chassis where it is at the moment.

This picture shows a measurement with the bracket removed;

I'll be working on a 58mm distance between the face of the bolt holes and the chassis bar. The reason I took the bracket off here was not just because it made it easier to measure, but because the bracket forced the engine crooked. The two holes are in fact central to the gearbox.The bolts to the engine appear to be M12, but I don't remember them being very long. 40mm between centres (typical metric Mazda!!), 3mm plate. This is the view from above;

From the bracket, this bolt hole is in line with the other two, and here I'm showing that it's interfering directly with the crossbar.

The rubber mount isn't complex. It's 38mm tall (rubber part), 77mm wide. Each fixed bolt is 20mm long, M10 fixing. That means a 78mm tall mount. If I use 3mm plate in front of the cross member, I have 58mm left of the mount to fit in a 58mm gap. That's a bit of a coincidence.

So time for a bit of designing...
