I have been rebuilding a 1940 Continental and started wondering about parts compatibility between other year/models when I found a full set of window channels and all the associated chrome for a 1941 Coupe. I wrote a few places, and no one could answer if they would fit or not. Being new to all of this (1st classic car project) I wanted to ask the collective subject experts if there are any parts that can be interchanged between coupes, zephyrs, continentals etc that are fairly universal to make finding parts a bit easier.
