B&M Shifter

I have a 69 cougar, which i recently acquired a month ago, it belonged to my best friend that past away 4 years ago. I’ve been tinkering with it, and he had installed a B&M shifter which i noticed it had come in contact with the headers, in short it stop shifting. I’m trying to replace it but i’m trying to order it before i take it apart. Anyone know the length of this shifter cable. That way i don’t keep ordering and tying up money. Any assistance would be appreciated. Thanks. Oh yeah that mirror was just on for looks lol. i couldn’t drive it without one risking a ticket.
