Regarding the provided wheel hubs

I have a simple question regarding the provided wheel hubs in the 2005 kit of parts that I have not yet found an answer for.

Are the hubs provided the same as those that were available from Small Parts, Inc. for several seasons? I am not planning on using or ordering hubs from Small Parts, Inc., but rather using a model of those hubs as available on www.firstcadlibrary.com.

The models available at www.ifirobotics.com provide the wheel, wheel hub, and associated sprocket, not as an assembly of four parts, but as a single part. That is completely useless for my needs.

Yes, they are the same.

then I take it they would be the same as the ones in these drawings?
