My driver's side seatbelt buckle sticks a little bit so I got a new buckle. I decided to spend $50 on the part instead of $500 through the dealership. Are there any write ups or anything on how to replace the buckle only? Do I need to remove the seat to do this? It looks like the buckle actually sits within the seat itself. Any other information that may be helpful with this? Do I need to disconnect the battery or anything like that? I appreciate the help!
