Stock adapter threads are booger'd up on the end, which makes it hard to thread oil filter on. 360 with dual exhaust with stock manifolds. Just a 3/8" ratchet with extension to remove/replace it with a new one?
I have one from my old 340 that has good threads with a square drive internal. I was able to get off via the engine stand with a 3/8" ratchet with some mite. I am not sure how difficult with the 360 in the car with the passenger side exhaust.
