Hi! I'm new to the site!
I'm also looking for cylinder studs (both front and rear) for my '78 550, except here in the US. Seems that they are hard to come by or maybe I'm just looking in the wrong places. I've tried Western Hills (they just have the rear studs 90033323000), the local dealer (who tried to order them, but came back empty saying that they are discontinued), and various other "racing" sites. I'm not particular as to whether they are an original part or aftermarket HD stud, just would prefer them to be new.
To answer the "why" question that you might be thinking...whelp, I snapped one while torquing down unfortunately. Which leads me to ask...should I replace all of the studs, since they stretch from torquing? I just don't want the same thing to happen again after putting on the jugs and head.
Help!!
Thanks!!
