non AC and AC vent question?

[rhyno811]

So I have a 78 Malibu non AC car and was thinking of doing a grand Prix dash... Can I just use my non AC vents in my Malibu or does the grand Prix have different vents? I have a whole grand Prix parts car, so I'm just making sure I don't run into an issue.

I used all the non a/c parts on my GP and they came from a 78 elky IIRC.... only issues is that the outer vents are non operational.. basically non a/c vents with a GP dash. as for the vent controls I removed the foot vent below the steering wheel and the controls bolted right in..
