A gated shift plate. From what I have read they don't really work. In order to make it so the shifter will go into them the openings have to be large and the gate fingers short. It's more cosmetic then anything. Not sure who sells them, if anyone. I know there was a thread here somewhere about a guy possibly designing one to sell but I don't know if he ever did.
Did a little search. Looks like it was this thread http://www.fiero.nl/forum/Forum1/HTML/078620.html
and ferrobi was the member making them.
