Does anyone know where I can find these springs? They are the springs that hold tension on the wire grid in the seat bottom. I tried to attach a picture but I'm not sure if it took.

I found a set of 73 Firebird horse collar bucket seats for my 67 and I'm in the process of making them presentable again.

Thanks in advance.

The least expensive and easiest way is to go to a good local mom and pop Hardware store with a good selection of springs. The wire size for the tension is what is important not the length, you can cut and shape it to size.
