Only a suggestion, but why not after having removed the engine, fit the rear facing starter and resting the engine on two pieces of 4 x 2" reverse engineer with that well known CAD Kellog sytem a flat vertical section in the rough position of the bulkhead, which is referenced off the false chassis timber. Once it fits nicely make the profile of the engine and starter from the Kellog CAD drawing and hold that up against the bulhead, mark around and it will be within a 1 or 2% tolerence I would think. Possibly "simples"? Unless that is I have grossly underestimated the difficulty, in which I suggest angle grinder mayhem.
