Ok so i know its usually the shifter thats the limiting factor, but has anyone used an old 7 speed LX rear mech on 8 speed? Ive got a really decent one and it seems a shame to waste it...
If you have very thick alu dropouts it might run out of reach for bottom gear, but Shimano built in a lot of extra so you are likely to get away with it.

No no and many times no! Irrelevant. The adjustment screws allow for a very wide spread, far wider than the width of a freehub, 7,8,9, 10 spd cassettes. That is why mechs from around 1986 onwards work up to 9spd without issues
