This is that $40 eBay one right? I got mine around the same time and it fit fine but I have a stock swingarm and caliper. So I wouldn't be tempted to blame the carrier. There is one thing I had to do a little different with the new carrier -- I think I had to screw the locknut down deeper. A lot more threads show on the collar on the right side. I really had to clean the threads of the collar a lot to get it to go that far since the threads had never been used.
