I had a thought regarding the panels of a seven. In some cases, the panelling is obvious. For example, the transmission tunnel is panelled on the outside for aesthetic and comfort reasons, the side panelling is also on the outside to make things look pretty. But why is the panel behind the seats done as an 'inside' panel? Is there any need for it to be a flat panel on the inside? Is there anything to be gained by putting it on the outer side of the bars?

Same with the panels by your feet, could those be done so the bars are exposed (and thereby gaining an inch or so space)?

It just looks better and easier to keep clean.

Looks better. Mine is fiberglassed from the outside and looks a bit ugly.

The footwell/transmission tunnel panel could be done inside the tunnel, but getting to it to rivet it in could be a bit tricky. And then should you ever want to remove it, the engine/box have to come out to drill the rivets.

The back panel is mainly because it's much easier to fit, and easier to keep clean. Any exposed tubes will gather dirt.
