Topic: 67 Shelby Running Changes Main Thread Findings

[J_Speegle]

Knew we would eventually have to start a thread on the running changes made to production 67 Shelby's during their production year. Many have already been studied while others have not yet been identified. As in the other Running Change threads you can suggest subjects here but we'll discuss them in satellite threads linked back to this main "collection" thread. Posts will be removed as the suggestions get added to the list below to keep this particular thread on the short side.

Remember that the 67 SJ Mustang Running Change Thread is also a thread to check for changes related to you Shelby that Ford had.
