The aluminum thing is probably cast iron and is the adapter for the Ultramatic but with it removed, the back of the engine should have the same bolt pattern as the others. The flywheel is likely the flex plate for the Ultramatic torque converted rather than a flywheel.

The 1950 and earlier had a single mount at the front of the engine with two on the transmission (one on each side) while the 1951-1954 had one on the transmission and two on the engine (again, one on each side). To put the 359 into a pre-1951 car, you’ll need to replace the front plate of the engine with an earlier one and get the front mount A-frame with new mounting rubber to use with it. I may have the plate and A-frame but I am not sure if they will work for you in this case or not since I am not sure what they are from.

As for telling R9 and R11 apart, they are quite different but another very recent thread from the last week describes them and is illustrated with photos of each. This site’s search engine will probably help answer that.
