Jack and support the car.

Wiggle rear manifold out the bottom.
Wiggle new rear manifold in from the bottom.

Slide clamps and crossover in
Start front manifold and wiggle/tap (rubber mallet) on crossover to seat evertyhing.

There's no need to pull the TB, air tube or airbox. It's that easy and that large of a car that you'll have an easy time. No need to drop the cradle in most non-W body cases.
