Redfox, Iv'e never priced a Camaro clip before but what rear Camaro is it from , is the steering box power is it in front or behind the A frame , are the brake rotors smooth or all trashed with grooves from worn out brake pads does it have 11 inch rotors and good calipers, hows the bushings look ?
If all this is good then 450 is a fair price I guess. If its all trashed your going to have to rebuild all of it before you can use it then 450 ain't so good.
You may want to rebuild it all anyway, bushings , ball joints , tie rod ends.
Take a good look at it .
