There isn't a lot you can use from the 520.everything mechanical is diffetent I think.gearbox and prop wouldn't be strong enough if you were to fit them but might work for a while.the Speedo needs changing and all the immobileser headaches you might have..suspension will need to be done too and you should ask the experts on here.cab,valdelis and others who deals with these cars.the 528 is a nice car .
