Thanks Slapshot,
I don't know what model of coin mech goes in the 400. I'm aware of a few, is there any way to know for sure?
I have the plate that attaches to the side with all the pre-drilled holes.
Would like to be 100% sure before I pull the trigger
You aware of any way to be sure what mech fits?
Post a few more pics . On more common models the mechanisms are universal..
