Suburban Headeds

[Dwn2rth76]

I am looking for some insight if anyone has some on this.
I found these headers online and am wondering if they fit? They claim to be for 67-81 camaro, 68-67 chevelle 68-79 Nova pretty much all the cars Where clearance is an issue. Has anyone ever used headers made for these cars on a 70-72 suburban? I have called several shops and no one knows. I currently have set but the collector sits right against the frame, and doesnt look like a shop has enough room to weld on to the collector.So im looking at trying a different set. here are some pics of the headers in question,Thanks for any info anyone can give! The picture on the bottom is The headers I currently have.
