How much is a Rear window defrost system worth?

Most are like that. There is a adapter that can put a speaker in also, I have that. Also the mounts are different for the motor plate itself on A, B,, C and e. Just subtle you can make them all work.
Thanks Ray, I was wondering what made my C body versions different.

For pricing, I've paid $80 and $130, I knew I paid too much for the $130 package.
