The RH side arches over the starter then curves forward to the mount. I'm attempting to leave the gap between the motor and the frame open for the exhaust to go through.
The LH side I realized my complicated mock up wasn't needed and I could just go straight across to the engine as there is nothing in the way (Gussets to be added later). The white pipe in the picture is roughly where the steering shaft will be (The pipe is a little low). The mount clears it nicely.
Unfortunately The motor shifted forward when the motor was tilted which can be seen pretty clearly on the LH motor mount shot.
