## Questions & Answers

**Q: Where is this cap made?**
A: always replace with factory part as much as you can

**Q: Will this fit a 1992 silverado 5.7**
A: As far as I know it was. My husband died back in March. I know he didn't send it back.

**Q: Please advice what filler neck will suite to this cap - 43mm/56 mm/68mm?**
A: 43mm

**Q: will it fit 93 corvette**
A: 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
