Smog/air pump removal on 87 350

[keg]

I want to remove the air pump and associated plumbing from my 87 350 1/2 ton. There are tubes on both sides that that go in behind the engine by the exhaust manifolds and I really can't see where they go and what is involved in removing them. Can anyboby tell me what is involved in removing these? Or maybe a picture. Everything else looks pretty straight foward.

I removed this from a 94 LT1 and had to fabricate a plate to plug a hole on the rear of the intake after I removed the smog plumbing. Just wonding if this would be a similar problem? thanks
