<VV> Should the EM bespoilered?

[Robert Hawley]

Howdy All,
    Speaking of spoilers:  are there any recommendations from the group on
aftermarket spoilers that might fit the EM (non FC)?  This issue is not
addressed in Corvair Basics or the Classic Corvair  that I can find.  Is a
spoiler helpful on the EM?  Has anyone had experience with the EM spoiler sold
by Clark's (page 313)?  I couldn't find a spoiler listed by any other vendor,
but would welcome any information you have to share.  Thanks in advance.
