I'm going to say the Tahoe is too wide for the early Suburban swap.

I've seen a couple Trailblazer chassis swaps and they are as wide as an AD truck can take.

With that being said, the Tahoe is a wider vehicle than a Trailblazer, so I can't see how it would work without widening your Suburban body.
