Tim,
I think that you can also use the same cover from that era VW fuse block too, cuz IIRC it was the same part with the same part no., which p/n you can get from the free pdf download of the 914 PET parts manual at the Porsche website > Classics section > Documents subsection.
IIRC there are also some nice repros out there with the VW shops too. Try at TheSambe.com, ISPwest, etc. for those.
Happy 4th!
Tom
