Drivers side window

Can anyone tell me if the roller that inserts into the window channel is a press fit into the drivers door regulator or if not how it can be removed. It looks as if the shaft press fits into the regulator but I cannot tell for sure. The car is a 1992 Cavalier 2 door with electric windows. I tried to twist it out with vice grips but only suceeded in twisting off part of it. Thanks.

I did both, thanks for the ideas
