fyi - found this on the forum before, since I have an 85 z51, thought I'd share.

My 1985 is not listed as a Z51, but it at least has those options. As far as the rest, I have not been able to confirm or deny them, as I haven't yet looked.
My point is: even if your car isn't listed as a Z51 in the RPO codes- you may still have most of the features.

In addition, mine also has Z51 stamped on the underside of the front lower control arms.
There's also a specific number stamped in the spring, but I suppose the exact number varies from year to year.

This answer was actually posted by another forum member in response to the same question sometime back. I thought it was kind of funny so I stole it! My car is an 86 and has the Z-51 RPO code, but it did not have the dual functioning exhaust.

Go to the Corvette Museum web site page for ordering a build sheet.
https://www.corvettemuseum.com/libra...ts/index.shtml With your VIN and $40 you can get a reproduction of the build sheet used for your individual Vette. You can also get a copy of the original Window sticker. It is nice to have and will resolve ALL questions.

DOH.....your right.....they are behind the seat in the storage bay.....
I had an 85 with Z51.....Liked it better than the 91 I had as far as handling. And yes.....the 3.07 gears in an auto is much better than the 2.73!
