Header melted the shift cable.

You are all pretty close. But there is a very easy way and method to prevent the melting of the cable with the correct routing. One holder plus a product to put on the cable.

Tools used were w 3/8 drill bit and a Crows foot. It can be seen on some of the many pictures of my Duster posted .

I have seen the inner cable push through just from radiant heat on cars that come here . It doesn't have to touch the header. I never had anyone return after we install the shift cable with any cubic inch motor . My car had 2 inch tube headers and space was very tight in there. There are some pretty smart members that know the correct method on everything. I am sure they will chime in now that they saw my input. Good luck. LOL
