I'm going to be asking about the c clips I need to fit my new canvas but just wondered if anybody had fitted a Devon canvas? I'm looking at the bottom part, how does it for to the roof? I figured it was just by using the c clips again but remember when I took off the old bellows 3 yrs ago that it was screwed to the lower roof section. Looking at it nor with a flat sided canvas I don't know how to secure it other than the clips and seal, any ideas? Thanks.
