Default changing non-vented opti to vented

Wondering what goes into changing my 1994 z28's opti into a 95. what other parts would i need to change besides the vented opti? and how big of a job is it?

thanks

I'm sure if you searched you'd find something. A trick my friend uses on his Vette is spraying the opti down with WD-40 before he washes his car. Silly idea, but wonder what Rain-X would do . . .

If they're FOR, they should be direct fits.
