Is there variation in rear derailleur mounting positions or is it fairly standard between frames?
I've recently switched a rear mech onto an old 90s mtb and now the jockey wheels won't clear the 34t sprocket on my cassette (but the same combo has worked fine on a more modern frame). It's not within the range that the b-tension screw can help with either.
Assuming the frame simply has a shorter mech hanger, what's the best new derailleur I could buy (9 speed compatible, with greatest possible distance from mounting screw to upper jockey wheel).
