I fitted the engine cover today. Thanks to Jeremy for the stainless lift-off hinges. The front edge of the cover is supported by a 15mm aluminium angle and the bare GRP edge is covered with tight 'n' fast. The lift-off hinges securely attach the cover whilst allowing it to be removed.

The picture below shows the rear bulkhead panels.  I've only covered the exposed tops of the panels. If you look carefully you can see the holes for the button head cap screws that will screw into the rivnuts. Not sure if I'd do this again as it is tricky to get everything lined up. A better compromise would be to rivet the panels on and fit access panels. 

Next time in the workshop,  cover the dash and fit the drivers side tunnel. Both jobs I have been dreading!
