At first i have no experience with costar stabs.
I noticed that my costar stabs only make contact with the front side of the U thingy and asking mysefl if this is normal/correct? I have already grindet the cutout in the backeplate somewhat.
I doubt that i have the stems mounted the wrong way because the other way around they dont fit at all. For all i know there is some play on them but doesnt that have to be on both sides not only one. Can someone explain please.
Pic stem makes only contact with front leaf:
Marked the said gap here:
Thank's for your help
