CB350 Replacement Rear Sproket

So I've looked the part number up on this sprocket in a few different places and it always indicates it's a replacement for my cb350. However the sprocket post are tightly press fit into the original but are completely loose fitting on the new one. Has any one ran into something like this or is this normal?

I have run into it before. David Silver Spares supposedly sells a sprocket that is machined correctly. The problem with a lot of aftermarket manufacturers is that they produce a sprocket to fit over a range of bikes. What I have done in the past, which may not be the most ideal situation, is to put a set of vice grips on the studs that go into the cush drive rubbers to hold them, then attach the nuts and torque them down.
