The upper line runs down towards the outlet then bends to the right around the outlet hose, under the hose and is attached to the lower portion of the radiator, then to the flex line.

I just completed a 5 speed swap on my 85 190D, so not able to send pictures. I have the lines if you need them, if yours is not the right part. Will send them to you at cost as they will end up in the scrap pile.
