PAIR block off plates for GS500. 2 of them. One side is made for an o-ring and the other side for a gasket or high temp sealer. I've always used the non o-ring side.
I ship them to LOWER 48 USA only and you send me $1 for shipping after you receive them.
sorry about the duplicate post - i didn't see the other one.
