Hi, I have a 79' Mustang 2.8L V6 Auto and I have a problem with my neutral safety switch always breaking. I've changed it twice and it only works for 2 weeks and then breaks again. The car is newly restored and i did put a new custom made exhaust system that changed from one single pipe to double X-pipe. The new pipe goes right under the park neutral switch and i was wondering if the heat from the exhaust is breaking it or something... does/did any of you have the same problem or know a way to fix this?
