[DeTomaso] Cobra / Shelby Club Race at Willow Springs / RearDeckLid Needed

[David in Durango]

I wonder if the deck lid is being pushed from below and/or sucked from above 
. . . (ah, the images) and when the lid is loose, is there less drag? less 
lift?

Cover?  what would that do to air in and around the intake?

Junior always was partial to fancy dismounts.

Who has a POCA membership list?  Please send Andy Wortman's phone number.

thanks,
