The cooler number given is correct per the parts book for a C75-C85-C90 where the cooler was hard mounted to the engine. What Cessna did was use the same 4763 adapter that Continental designed and instead of hard mounting the cooler to it, they installed a plate with fittings to connect hoses to, and then mounted the cooler to the baffle, as seen in the previous Ebay listing. I don't see the adapter in this one, It looks like the cooler, mounted with three studs INLINE with each other, but onto some sort of casting with fittings, probably for hoses. This does not look like the 4763 adapter with a cooler bolted to it. Look at fig 17 of the Continental IPC for their installation.
It would be perfectly legal to install a complete Cessna 150/O-200 oil cooler installation on a 150 of the models for which it was available, either originally or as a Service Kit, with nothing more than a log book entry. Installation on other models would require a field approval I would think.
