    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.

    Ouch! Those look worse than mine!!.

    I called the local GM dealership. The bolts are a discontinued item but they were nice enough to give me the size. M12 1.75x45. It didn't list fine or coarse threads but I am sure I can find something to replace it with. I wonder what bolt strength these are. The dealer parts department didn't know that either.

    I appreciate the listing.

    A 12mm tap with the same thread count and pitch should be easy to run down there and clean it up and the same for the chase of the threads.

    I was wondering if I could do that. A chase will be hard to find in my area but a tap is easy enough to get. I will get one and gently try it.

    Great idea. I had not thought about that. I just checked and our local Autozone has a thread chase set for loan. I will get it tomorrow. I will report back here with pictures good or bad in the next few days with my rebuilt seat installed.

    The 1.75mm value in the bolt spec is the thread pitch. Besides the 12mm size, that's what you need to know to get the right tap/chaser.
