I have a used cruise control regulator for sale (that's the GM term for them from the 60's, I've always heard them called transducers). From what I have seen over the years and what I can find in parts books, it appears to be correct for 1967-1968 full size Canadian Pontiac and Chevrolet, Chevelle and Camaro as well as 1968 GM pickup trucks.
I don't know if it works and I don't have a way to test it. However, it is not seized, the number one failure which these units experienced. It looks old but nice, not all rusted up etc. There are places online that rebuild these units. This guy on ebay with a number of rebuilt units for sale does custom rebuilds.
Here's a 72 Cheyenne Cruise Control Unit (glove box door documentation showed it being original), it's now in my possession and will be installed in my 72 Sierra one of these days:
This is the one in my 69 Chevy. it is not original to the truck though so what year it is actually I don't know. it was added by the guy I bought the truck from 20 years ago (wow!) and worked for a little while.

Excellent photo Ken, it shows me where the vacuum line & wiring go through the firewall.
