Replacement emergency brake cable does not Fit

I took my 05 Dodge stow and go to a professional mechanic he called me 3 days later and showed me multiple boxes from different dealers with e-brake cables then said he gives up! He was the third mechanic I tried.
(I told him he was the first) he said the same thing everyone else is saying the replacement cables don't fit. On the internet I read they make a mounting bracket that makes the cable fit. It's aftermarket and I heard it's been discontinued which doesn't make much sense. Again, these mechanics haven't heard anything about this or have given me any insight as how to fix.

A fourth mechanic I talked to told me to bring it in to his garage and he said the other mechanics don't know but they make an extended cable!
I'm not sure if I believe that!
