Looking for some help here. I am upgrading Shimano Acera 8 speed rear derailleur to 8 speed Shimano XTR rear derailleur and it appears that because the old 8 speed XTR derailleur has a clip for the tension of the b-screw that keeps the derailleur from sitting flush and looks like it is not compatible. What am I missing here? Is it a compatible swap?

1Hello and welcome - I imagine it would be fine, but definitely need a photo to show what you're up against.– Criggie ♦Jul 11 at 19:27

Many higher end Shimano derailleurs have had the circlip in question to allow disassembly and maintenance of the pivot bolt. RD-M900 (8-speed XTR) is one of those. In some (maybe all, not totally sure) of these designs the circlip will be the thing that rests against the frame, that's normal.
