My 2001 Yukon needed to have the driver seat cushion replaced as you can imagine. With 412,000 miles it was a little flat. I got the seat out but one bolt gave me a hard time. The rear outboard 14 E Torx bolt didn't want to come out. I had to put a breaker bar and plenty of oil to get it out. The bottom threads must have been rusty since they go through the bottom of the floorboard. The threads are a little messed up on the bolt. The threads in the floor look ok but I am sure they could use some repair. Does anyone know what size they are and the correct chase to use? Or should I see if the dealer has replacement bolts and use a new one to chase the threads. Thanks in advance.
