If they fall though I have one laying around also, has 10k mi max on the rebuild, rebuilt with the 360' thrust bearing, I would spike 19lbs all day in my SR, no issues.
Also have the OEM outlet flange and a never installed ISIS screamer one, the ISIS one I had powder coated black but then it didn't fit with my 18g so I went to a normal bell-mouth one.
All has just been sitting for almost a year, PM an offer if interested.
