rear seat, how much weight savings?

There is also the braces that the seatbelt assemblies hold to as well, those have to have a little weight to them as well. I am going to get a spotweld drill and remove them, has to be good for a few more pounds. The seat bottom is almost weightless, but the seat backs have some weight, but a lot of it is in the seatbelt rolls, brackets, and other BS.
