The round puck at the back seems straightforward enough. That part will incorporate a trailer hitch receiver.
The crossbar (part 52380x) at the front runs over the mount with the mounting bolts pointed down. A straight bar with the bolts pointing up into the sheet metal and tied to a 4-point roll cage would be one option. Another would be to use the stock crossbar and stand it on a T-shaped leg on the stock forward transmission mount or on a bar that runs between the rear upper shock mounts. There are some handy lightening holes available there. Or both. What do you think?
The MGR has (essentially) a single mount at the rear with two wide-spread at the front and hangs from above; while the original VW transaxle is the opposite. Too bad I can't just turn it around, upside down and backwards.  |
Looks like you've got it under control.
One thing their design says to me is that the resultant load from the MGR's torque is a much greater factor than its weight. I would be very leary about attaching anything like this to the sheetmetal. The roll cage or the stock transmission mount seems like a good idea. If the stock VW transmission mount were used - assuming the transmission support is below the MGR - then the main loading from the torque could be in tension and buckling wouldn't be as much of a factor.
Also - polyurethane bushings are readily available for many motor mount applications. I used some that were made for a Mitsubishi Eclipse for my Yota Diesel conversion. The only problem is they are too stiff - you really feel the diesel.
Anyway, they would probably be just fine for an electric motor.
Take care,
