hey, my lil bro recently got a 1965 6 cylinder mustang. he needs to replace the spark plug wires. i called up the auto store and they said they have 2 different size 6 cyclinder engines. my question is does it matter what spark plug wires are used, and if so how do i find out what size 6 cylinder engine it is. thanks

1966 Mustang15

no there is no difference a 170 and 200 were all they had in them and they are the same
