There was a time when only a few manufactures were out there and this could never happen. tod74 has shown another possibility and I will bet there are more to choose from. The color matches better but they have a # on them? Harland sharp rockers cost me $180.00 for a set in 1985. I pay that much for 2 Jesell rockers today without hardware. Harland Sharps have not gone up in price much since then. Either I got ripped off then or they are junk now ......... or both. Get a set from another manufacturer that are rated for the spring pressure you are running then go one higher and you will be all set.
