Default Adapting 90mm TB To MAF?

What is the cleanest, most professional-looking way to plumb up a 90mm throttle body to the MAF?

I bought a F.A.S.T. intake/90mm throttle body for my engine re-build. I also bought an '03 Z06 MAF. Is the Z06 MAF a 75mm unit? I know it's smaller than 90mm, and it just struck me that I need to come up with a way to plumb this up without looking like a barn-job. If I need parts, I'd like to get them now.

My block is headed out to the machine shop early next week. When I get it back, I want to have EVERY part I'm going to need to reassemble the engine. The only part I can't "pre-order" are the pushrods, as I have to check what length I need before I order 'em.

Has anyone installed a 90mm F.A.S.T. intake, and, if so, how did you plumb it up to the MAF?

The z06 MAF is 85mm. Do a search, you should find some more information.
