Ron is absolutely correct. The body for the last version of the Ace differs from the 289 Cobra only in they were missing the flat flare of the slabside wheel well. Those were added, presumably based on discussions between CS and the boys at Thames-Ditton, to accomodate what were going to be six inch wide wire wheels to hold wider rubber, rather than the Ace's 5-inchers. The front clip, however, was not changed. The pretty small-block Cobra shape is pure AC.
