85 Trans Am lower duct?

Hey guys, finished painting most of my GFX pieces, and came across something odd. When installing the fender GFX, it looks like the tabs on the end are supposed to bolt to a piece in in the middle, underneath the car, right in front of the radiator. I see remnants of a piece of plastic bolted along the radiator support, but whatever it was, it is snapped off except for the bolts and some small pieces of plastic still attached to them.

Perhaps a dumb question, but is there supposed to be some kind of duct down there, or a plastic cover? This would be directly below the front pullies. I always wondered how ram air got to the radiator for cooling, am I totally missing a duct?

Did a bit more research and found what SHOULD be there (the air dam). Does anyone have a pic of the 85 TA style? Want to make sure I get the right one.

Get the later 3 piece style. GM improved the design after the fact.

I see what you mean, Hawks has them pretty cheap. Thanks for the heads-up Drew
