And yes, FoMoCo was not super psyched about a Willys (!) platform, OG's winning ways or no. Can't really put a 35-year-old competitive product in a race-win ad.

That discussion led to the famous Mustang gasser of song and story. The race body was the fiberglass released-surface model from the Ford styling department for the '67 model year, detoured to Ohio for mounting on a Willys chassis, OG's choice, have heard a fabricated frame was verboten in AA/GS.

Ford donated other surface models to drag racing - the '64 Falcon body became an A/FX, and the '65 LTD that became the "Snoopy" flip top FC.
