Are 300D Elec. Window Regulators good on a COUPE?

[Jkrome]

Just as the title says, im facing the woes of replacing my regulator on the front passenger side of my 1980 300CD.

I found a few possible matches on ebay ranging from 70-130 , way under the OEM price of 400+. Apparently these suckers are tough to get.

Anyway...So here is the part.

I called the ebay company to clarify and couldnt get the question answered about the part number... Their's is listed as 126-720-2846...

This auction claims the part is *specifically* for the coupe 123 regulator..
I just dont see why the part would be any different for the front door on any 300Diesel...

2646 on this one...hmm...

If anyone could clear up the confusion so I could get my dang window up finally...id really appreciate it.

Also, one of my rear windows on the coupe is stuck....Would any of you know if a 280CE quarter window regulator such as this one:
