Blazer vs. suburban tanks ???

[Alias137]

I know the blazer tank is a popular swap, and seems fairly easy to do. The local wreckers only has a blazer tank from a diesel blazer, so I kinda don't really want it. My question is though, would a tank from a suburban fit the same? The physical size looks as though it is the same, and it sits inside the rear frame the same way. Has anyone used a 'burban tank instead of one from a blazer? I'm thinking I might pick it up tomorrow.
