Thank you, Guys.
I did small things today, like hunting for a water drain petcock for the lowest point in the bottom hose/pipe, with no success.
I bolted up my new rad outlet and mounted the 90* rubber hose, [first pic].
There should be a lower wind baffle at the bottom of the airflow to the rad, so I found one, fixed it up a wee bit, painted it and bolted it on there, along with a small crank bracket. [second pic]. I don't have a crank and the crank nut in the front of the crankshaft has morphed into a drive mechanism for my hydraulic pump; but I have a crank centering bracket.
