Bill,
That's the way the radiators were mounted in the picture. There were also braces behind the radiators at the bottom connecting them to the engine mount plate. I flew for awhile with that configuration but after doing a vibration analysis, I removed the
mounting tabs connecting the tube to the reduction drive and also removed the braces to the engine mount plate. Instead, I mounted the bottom of the radiators to the engine mount (not the engine) and installed tubes from the top of the radiators to the upper
mounting point at the firewall. All four mounting points at the radiators are fitted with rubber vibration isolators. The radiators are completely isolated from the engine and reduction drive and removing four nuts allows the radiators to be removed as a
unit.

Does your fixture holding the two radiators just bolt to the redrive in two places ( at the top?) With this, can you remove the units as a set and have them back into position on reinstall without a lot of fuss?

I machined an aluminum block that installed at the stock oil filter location that allowed attaching the original oil filter base pointing downward and also provided oil ports for oil pressure and temperature sensing and oil supply to the reduction drive.
This has been reliable for over 300 hr. Just a data point.
