Thanks, I saw the one from Classic. Not sure what the differences are but its the original 78 carb so should match up. Must be fairly recent, it always seems to be missing from other catalogues.

EFE....good luck.  Sometimes they come up on ebay.  TVS switch goes into the air cleaner.  EVE-CV is just a check valve and can be found.  The TVS still can be found....PM John007 he just bought one and had a hard time getting the right one.  The thread sizes can be different.

I had this one in my 79 plugging a hole.  I swapped it for a brass plug and put it in the 77.  all I need now is the switch in the front of the intake. 






all I need to find now is the correct rubber tubing.

Try Corvette sites for the correct striped vacuum lines. I'm trying to figure that one out right now too. Some were yellow, others pink, and some were green stripes.

Weren't the colours simply different inner diameters, to make it easy to ID on the production line or whatever?
