Terrano Oil Filters

Just wandering if anyone has had any problems obtaining a oil filter for a Nissan Terrano. I have a 1990 model with a TD27T. According to the Ryco catelog either the Z503 or Z416 filters should fit. I bought a Z503, and the thread was too small, so I then bought a Z416 (Repco doesn't like to exchange filters that are a little dirty). This time the thread was correct, but the anti-drainback valve protruded so far forward that it stopped the filter from screwing in by about 5mm. Anyway, after much reseach (and an angry Supercheap drone who could not understand that what's written in a catelog does not neccessarily translate into reality), I found a filter that fits perfectly. It's the Valvoline V049, it's exactly the same as a Z416, but the anti-drainback valved in recessed further into the filter...fitted like a glove.
