Thanks for answering.

I'm not sure I understood.
There's a photo of the front of the tuner chassis (if this is what you meant) on the page 1 of this thread, and the only shafts (pins for the bumper grommets) there are all have the grommets on them, a different kind.

Also I don't see any rails: the chassis sits on the wood shelf directly (with the cushioning grommets underneath).
Could you somehow show what you have?

And is there the single screw at the center of the back of the chassis that holds it? If yes what size/length is it?
