I was over on Pinterest checking out pictures of the BO29 Cuda's and came across this picture of the test mule car... Anyway it says "this is the 383 67 Plymouth Barracuda that became the test mule for the 68 hemi cudas and darts then it went on to be sox and martins car" under the picture.
Is it true that it became a Sox & Martin car?
