definatly clutching lol
the zed hand brake shoes are the same for the E46 for 2 - 2.8 liter because they all have the same size rear discs, the 330 has alrger discs so will need larger shoes
there is some hope though, the pivot is the same: http://www.realoem.com/bmw/partxref.do?part=34416750198
the adjuster appears to be diffrent: http://www.realoem.com/bmw/partxref.do?part=34416851437&showeur=on
the springs dont have individual pn's on the zed so cant tell if they are diffrent
i will measure tomorrow, the hand brake shoes were under £20 at europarts anyway,
yes the fronts were a straight swap, i had Stainless steel braided hoses to go on so that made it easier too, didnt lose to much brake fluid
