Suburban Seats In A Crew Cab?

[GMC85HighSierra]

Has anyone tried putting both the 1st and 2nd row Suburban seats into a crew cab? I have a 1988 crew cab, and I came across a set of pretty nice 1978 Suburban seats. The front bench has the usual wear on the driver's side, but it isn't ripped (yet). It's at the point where the fabric is starting to get thin. The guy has the 1st and 2nd rows but not the 3rd. he also has all of the brackets for the seats, including the ones that lock the seat backs in. He's asking $25 for them; I know that's cheap! I'm just not sure how well they'll fit in my crew. Any help is appreciated. Thanks
