Being a sucker for originality, I want to re-install the hot air intake (heat riser, I think) used during cold start: the hose under the air filter box and the metal piece on the exhaust manifold.

1971 W114, 250 (M130 2.8 engine)

I bought the part that connects to the exhaust manifold, A0000941211:

Part numbers I found here: https://nemigaparts.com/cat_spares/epc/mercedes/1/m/130923/036/09/001/?chasis=11401168B

I figured once I got the part, mounting would be "obvious"... but I'm not seeing it. I looked through my many technical manuals (Mercedes engine, Mercedes Chassis, Haynes), but none show enough detail.

Does anyone have a picture they could share?
