Hey Shane, if that's all you're a lucky man. I think it's mandatory for all 75s to have a leaky rack, I've had to replace the high pressure hose but the rack itself still leaks but not too bad.Not sure about the engine mount, you might get enough movement in the drivetrain to do as you have suggested, somebody else to advise here....As for the do-nut, you should take a good look at the clutch and the other do-nuts as this is a good time to do it all with the half shaft out. if you take the entire prop shaft out you might be able to do the engine mount too... lotsa work lotsa fun.....another Alfa moment.
