I found this one - Chinese made - on Ebay. I bought one like this. It worked fine. There seemed to be many more cheap, aftermarket options when I bought mine a few years ago (Tarrifs?)
Anyway, mine was black plastic and it accepted the thin chome-colored plastic trim piece that was placed over this part. The trim piece covered the en tire length of the grip
