Oil filter puzzler - looking for correct filter 914-6 Options

[roundtwo]

Hello,
Bought a newish to me 914 with 3.0 liter engine with an oil tank installed. Tank custom stainless from Ben M. He wasn't the supplier for the oil filter base plate.
Can't figure out what oil filter fits the oil filter plate that's mounted on the tank.
An OC28 filter has the right 17mm threads but the filter is too small capacity wise. The base size of that filter looks correct. I need the larger (longer)filter.
Tried OC 54 filter but the tread size was incorrect.

Any clue what OC filter is correct? Of course I don't know who manufactured the filter plate that mounts on the tank. I called pelican but they don't have thread size specs for the oil filters. Usually they have all the answers to esoteric questions.

Ok experts!!! Any ideas here?

Thanks, Todd

Thanks for the clues.

It’s the filter for a base like the one picture but with a 17 mm thread not a 22 mm thread.

Apparently, this consul bracket is available in different sized threads that accept the filter. It doesn’t have to do with the engine size/ year / model of the car - it has to do with this consul that’s mounted on the oil tank reservoir.



Just need the 17 mm vs the 22 mm pictured. Patrick Motorsports sells just this one.

Still looking for the bread crumb trail.
