Canvas Roof

Welcome to the Open Forum, Keith.  In what area are you located?  There is a slim possibility that one of our forum members -- or a Hudson club member -- who has restored a '27, lives in your vicinity.  You might then be able to visit that person and get some pointers firsthand.

Although a bit premature, Here's a source for the roof insert material for coupes or sedans. I hope this is useful to you....and, I hope I did the link thing correctly. Sedan version shown, coupe is a little less $.
