The original cable from my 67 Barracuda (273/904) was 60"... just measured it yesterday. I remember seeing several cables while looking through the catalog Tuesday down at the parts store, but I don't remember if any were less than 80". Might be worth a trip to the parts store and asking to see their Pioneer catalog that has all the cables. You can look up the exact application you need, and then compare ends on different length applications. FWIW, 80" will work, but you have to work on keeping it up tight to the body and not touching the exhaust a bit.
