RH drive car, looking for remote oil filter options

Since the factory adapter is already in place, and it doesn't leak; you're already miles ahead of where any aftermarket kit will leave you.

True, but I sure wish that one fitting wasn't right next to the transmission bellhousing bolt, as it makes working on the car that much harder. And if I do keep it, I don't know that I'll be able to safely move ("re-clock"?) it.

Just not sure what to do. Maybe I'll leave things as-is, maybe I'll replace everything and start over, maybe there's a RH specific (not "universal") kit from Down Under that will work....
