One can't approach parts purchases nowadays as though they're gonna be OEM-equivalent, let alone perfect. Good used - and good luck with that - or NOS, or a quality manufacturer like DMT (71 TA here) are the only hope. Americans arguably brought this on ourselves...how many times for example do you see a post here looking for "cheapest price" ? But I know the aggravation of paying up for an item that initially looks good, but is either a problem to install, or fails quickly.
