Technical 41 Willy's sedan

Hello hambers. I read a lot from the hamb post very little. I'm doing all my homework on converting a 41 Willys sedan into a 41 Coupe. I found lots of little bits on doing a 40 or earlier sedan because it's easier. Trying to locate or find information specifically on someone who has done a 41 has been difficult. It's obvious to me the rear section is going to be the most challenging part. My initial thought is to use my sedan rear fenders and then start fabricating what I need to fill in the spaces including the window openings. So my question is, does anyone know of anyone who's done the 41? I will definitely photo do***ent this conversion to share with the rest. I'm still several months away before I can even touch it which of course is driving me crazy. Thank you in advance for anyone who can help.
