If you strike out on eBay, Franks, and the other normal sellers contact Steve Barcak at Pontiac Heaven. He pulled off and sold my buddy a center vent from a '68 out of his yard and might have the remaining pieces. So weird about all the different ones used in 1968 and really narrows the odds of finding the correct one.

 

Thanks! ill look into that

 

That "parts guy" has one but he wants $220 for it! And I'll be rolling the dice it's correct

 

Here is 69 ac parts.
Not 68. Or 70
69 lap vent air intake from the heater core box is a rectangle
68 one side is shorter
To me it looks like you have a 69 lap manifold and a 68 duct
How about a picture of your 68
Heater box to lap manifold opening
