It looks like your car was pretty loaded from the factory. I would try to get a Chevy 10 bolt they are cheaper and a little stronger. But if you want to keep the car original I would keep the 8.2. Its hard to read some of the build sheet but it looks like you have power bench seat power windows locks block heater trunk release defogger tilt and map light and some other options. Does the car still have all these options.
