I am in the process of installing a subwoofer under the rear seat of my 03 extended cab f-150. I need to take the rear seat out for some working space and running wires. The bolts that hold the seat belt down will need to removed, I belive I need a "torx bit"?

Does any one know what size I will need? None of my friends have the correct size and I don't feel like playing trial and error buying out the hardware store.

Thanks,
Dan

 

The seat belts should be a T45 or 50, I forget which exactly.

 

Its a T-50. The hardware store was nice enough to let me test fit the bits before I bought one.

Thanks anyways.
