I believe this fiberglass part may belong to a Crossle 42/47 S2000, air scoop located behind the (front) radiator, but not 100% sure.
If anybody can identify for sure (and is interested in the part) please advise accordingly with PM.
Part measures 23" wide at bottom, 10" tall sides, 12" tall overall, 15" overall depth F-to-R, 2 threaded inserts in the bottom
