Where is this cap made?

always replace with factory part as much as you can

Will this fit a 1992 silverado 5.7

As far as I know it was. My husband died back in March. I know he didn't send it back.

will it fit 93 corvette

The picture looks nothing like the RC27. It's metal not plastic. Sorry can't help you with the 93 Vette. I used it on a 93 Cadillac Deville with a 4.9L V8. Not sure if it's to your application, but if yours is plastic - this isn't the one for you. - John
