airbox help

Hey Pelican gang. Disclaimer, I'm not a 911 owner. I Love them, but don't own one yet! So, I have a rookie question for you guys.
I'm powdercoating some airbox pieces for a client with a '68? 911. He dropped off the piece shown circled in the drawing. I pulled this picture fron the net but his is similar.
How do I separate the plastic center piece with the 90 degree elbow from the metal exterior? I see 4 bumps and I wonder if the piece is plastic welded from the factory. Should I drill out these areas and rivet back together once powdercoated? Am I on the right track? I'd hate to damage the part.
Thanks for any disassembly help.

I don't have that style airbox on my vehicle so I can't give you any specific help but, I can say that if it were my car, I would want the powdercoater to let me know what they plan to do before they do any disassembly that requires removing rivets, welds, etc.

Thanks Joe. The owner and I have already spoke and are on the same page. I've got the go-ahead from him already to do what is necessary to remove the inner piece. Just wanted to remove it as carefully as possible. Hence the question.
