300TD-4-speed

Hello All,

I have a 1982 300TD European spec car with manual windows at all four doors. The front passenger window drops like a rock if you so much as move the hand crank down (it stays wedged up if you keep it cranked tight).

My question is, I can find manual regulators all day on Ebay, but they are for 240D. Does anyone know if it's the same part used in my car?

Thanks much!
