I pulled out the locating pin and bolted the puck where it belongs. I can't imagine it's going to move.
Did the same thing here. Forgot all about it...Curious as to why it doesn't fit...seems like there's quite a few people that ran into the same problem.
I have installed several Magnums and a few other systems and I have always dremaled the roll pen off, and installed the block no problems on any of them moving.
