Front spoiler on 68s-did they exist??

[jims427400]

I baught a front spoiler to divert more air into engine but noticed there seems to have never had one to begin with. I thought they all had spoilers but my car is very early production #320.
Even looked at the CAC gallery and was surprised to see these photos w/ no spoiler.

I hate to drill attatchment holes into something that may have never had it installed. My front valance appears to be original,even has the hand cut openings for cold air cooling.

Frt Spoiler

Jim,
The attached pic shows a front spoiler (or extension), my car doesn't have it either.....it does however have the two cutouts shown....
The drawing date is 11-28-67 so it is possible that your car, as mine, was built without the extension.....
Maybe someone like JohnZ will chime in and answer this for us.....

Cee,
What build # is your 68 ? And do you have the "hand" cut cold air holes?
In looking closer to your attatchment, my valance isnt made that way,my spoiler is already molded into the glass.

# is 1617, delivered in October '67...
There is no telling....from what I hear, they had problems with overheating on early production cars and the fix was the 2 holes and the spoiler....mine is a small block base motor so really not an issue....may be for you BB guys...

I'm sure JohnZ would know the asnwer to this...

The front valance with the holes in it and the chin spoiler were added to all BB's starting with VIN #720, and a TSB was issued to the dealers in February, 1968, to add them (plus a full fan shroud, new fan clutch, changing the vacuum advance source from "ported" to full manifold vacuum, etc.) to all BB cars built before #720. Not sure if (or when) similar changes were made on SB's - the big problem was the BB's.

My smallblock 68 with AT has the spoiler. #416660 with I20 build date. Also has the holes in the lower valuance panel.
