I've got a set of BC cook overs that have about 2500 mikes on them. They've just been sitting for last few years and appear to be in great condition. Spring model/rates shown in pictures. 16 front, 10 rears. It made for a firm yet comfortable ride. Just a lil stiffer than they come with from BC usually. Custom ordered. $600 plus shipping. Low ballers will be laughed at and then ignored.
