Buy two metric bolts to match two of the ones that attach the engine to the gearbox (one at each side) grind their hex heads, and cut a slot with the Dremel to facilitate their removal afterwards with a thin flat screwdriver, once you bolt these 'studs' to the engine you will be able to 'hang the gearbox on the studs' and the gearbox will slide right in position.. it is amazing how easier it will be!
I have used this tip at least 3-4 times within the last 10 years and always worked like a charm…
Thank you FCP..!
