Howdy folks. I'm working on rewiring my 1941 Town Sedan. Mostly smooth sailing so far, I am using a YNZ harness and that has been nice and the front of the harness is mostly installed. I am running into an issue with wiring removal in the back though. With the taillight harness that runs through through the A pillar on the roofline and down the C pillar, I have most of the wiring free and out of there clips, however something is caught up in the A pillar. I cannot free three wires that run through it. There seems to be something in the pillar making them stuck, but I cannot access it. The wires are completely stuck and have no give in either direction. Does anyone have any guidance on how to free them or how to access into the pillar??
