Yes...it looks like they replaced the center gobble hole with a pop bumper, or maybe converted it to a rudimentary kickout hole...what's the topside of your PF look like? Have you compared that to IPDB's pics of those topsides?

I agree Benhurr - they cut the center subway ramp that returns the ball from the center gobble hole, and that switch the OP was asking about used to be on the cut-out portion of that. So I'm assuming they did that so they could turn it into a pop bumber(that's what it looks like from the bottom to me). I was just speculating it could also be a kickout hole, but from those views the OP provided it doesn't look like the right hardware for a normal kickout assembly.

So I was wondering what the topside of the OP's PF looks like...I'm hoping they're able to reverse that hack, and REALLY curious about what that hack is exactly.
