W124 chassis...What is the inverted "U" shaped rubber/flaps thing on the underside of the tunnel, just above the flywheel/pressure plate in the pic? It passes through an oval-shaped hole in the center of the tunnel, and the "flaps" (drains? vents?) extend around either side of the transmission. Is this a drain for the evaporator? I have yet to find a forum-post specifically identifying that component, or find a replacement part. Mine is brittle and busted and I am in need of a replacement

You don't really need them. They just keep the water off the top of the bellhousing and reduce the chance of critters crawling in.

Those rubber penises are the drain for the blower compartment! The evaporator has it's own drains a bit behind on top the transmission tunnel, two spring reinforced foam-tubes, left & right. And if you look close - just behind the rubber dongs, where the panels join, there is an opening. This is the drain for the comparment where the brake booster, battery and ECUs etc. sit.
A/C evaporator drains (left & right):

^A/C drains not shown, car without A/C!!
And the drain behind the brake booster (not visible with booster installed):

Got enough drains?

The foam tubes are very brittle, though. If you don't have too, don't touch them. MB Part number is A1408300196. About 10€/piece in Europe.
