I have a roof panel that I bought at a swap meet recently, so I don't know what it came from. I think it is a 28/29 panel (see picture below). I thought coupes and tudors used the same roof panel, but now I am thinking there is a difference in the two of them. My panel is 29 1/8" long and 9 1/2" measured around the rear curved surface. I noticed on my 28 special coupe the length is the same, however the curved area is only 8 1/4". I think I must have a tudor panel as it is larger around the rear part. Does someone know if coupe and tudor roof panels are different. They sure look the same except for the curved dimension. Thanks for any help.
