As for them being all the same, the Ford parts book list all different one for 71-72 by production dates. For 1973 they list one for 2v carb and one for 4v carb. The part number for the 2v cable is D3ZZ9A758B and the 4v is D3ZZ9A758C. Go to
www.partsvoice.com and chose ford and enter part numbers. I checked and they are both available but I don't know which one you want. RAY THE PARTS MGR.
