608246 was the level and drain plug for all axles and level plug for t/boxes, tyb5 is the same but with a magnet attachedThanks jamesmartin, that looks right.
Quick question: On the parts diagrams I have, the only mention of tyb500120 is the front axle drain plug on a Puma. Is this the original TD5 era part, or is it coincidentally the right fit?
