Hi Mike. I have an M. I don't think the exact parallel alignment is an issue worth bothering with since there is quite a bit of play anyway. The main problem is have is that the rudders on the m turn further in one direction than the other. I think this is so with all of them and is due to the fixing bolts pushing against the ports side stern floatation charmber. I have thought to adjust or lengthen the tube but haven't managed to work it out without mucking something else up. The best idea I have would be to enlarge the hole and put a great big rubber sleeve on it. I've heard of people doing something similar to reduce the scratching sound and also to reduce water ingress along the metal tube.
When sailing or at speed there is no problem only when making a tight turn in a marina or river.
