There should be a white sticker, on the radiator top cover. It is a required sticker, for smog purposes. If yours is missing, you can go to your local Chevy dealer, and get one. I actually remember a factory campagne having to replace some of those.

If your speaking of the vacuum modulator for the transmission, they no longer use them on the transmissions with overdrive and electronics. The powerglide, turbo 350 and turbo 400 used to use them.
Try Your Local Automotive Store or Buy A Book On That Vehicle And The Diagram Should Be In The Book < $14.00 -- $20.00 But Make Sure Be You Purchase It.
Is the vacume for the distributor TIMED vaume or full vaume at idle???
Yes, you sure can.
