Why not keep the 964's oiling system: mount a good oil cooler up front in the center of the valence, where it will get a good flow of air (maybe purchase an aftermarket spoiler set up for this). Figure out an adapter to get oil from your tank to the engine.

But if you get desperate, I can get up off my d*** a** and measure the bolt spacing on the older style cooler. Though you are right - you'd have to backdate your engine cover. And maybe the engine oil thermostat also? Does the 964 even have one of those? I can measure the OD of the older style easily enough, as I have several spares.

Chances are pretty good that the earlier cooler will fit, since guys put the oil filter piece from 964 and 993 motors onto their earlier cased 911 race motors.
