Yes, that't the company.
I had some "extras" made at the time. Don't know how many you need or if you are replacing all of them. If you just need a couple, I can send them to you. If you want to have some made, I can send one of my old springs to you or directly to the company.
Give them a call and let me know what you want to do.
