Mixing up the front sheet metal

[Storm Chaser]

My buddy asked me about this but I didn't know the answer...

He has an 86 Suburban and a tree fell on it damaging the hood and tops of the fenders. He likes the look of the late 70's front end and wanted to know if it would work. I had bought a parts truck once where the older front was bolted on to the newer truck, but they had pried the hood up in the wiper area to clear the wiper arms.

So, I guess the question is- is there a way to "correctly" make this work? Is it as simple as changing out the wiper transmission, or is there more involved?

I already know about the frame horn/ bumper mount difference. I'm just concerned about the sheetmetal (or what we call the doghouse up here). Thanks.
