You are missing a plastic duct that bolts onto those 2 holes at top. I have a pdf file (adobe acrobat) of a page from a chevelle assy manual. I'll try to e-mail it to you.

I'll try this reply thing. You're missing a black plastic duct with 3 openings for right dash, defrost and left dash hoses.valley1494@juno.com. I'm looking for the two brackets that attach the condenser to the core support. E-mail me and I'll reply with 2 pdf files

You're also missing the bracket the duct assembly slides into it appears.
