I have looked for this but I can't find it anywhere. It's a valve on the hose leading from the intake manifold to the opti, the bigger one on the end. It's for a 97 ss. <http://shbox.com/1/opti_vacuum_hose.jpg> Mine melted against my exhaust manifold. Can anyone tell me how to get my hands on one, other than junkyards, can find z28's anywhere. I apologize if this is not the right place to put this thread. Thanks for the help.

 

While your were at Shoe's sight, you had the number and didn't realize it.
