More retro bits-Need opinions

[Uber Affe]

OK...
So here's my idea.
Porsche Spyder type louvered plate. ( I really like it)
I could make it out of a spare 1303 front end.
the other thought...A removable rear apron.
I will definitely do this, but does it look stupid in a bare metal finish? Same color?
I wanted to put holes in it and someone recomended louvres instead. I think I like it better just plain, but if I go with holes it might look a bit funky.
I don't think I like the "venting". Holes still look better to me, but a solid piece seems to be the best especially if itis going to be removable.
Any thoughts?

thanks,
