Thanks Greg, the pix are very helpful. It appears that the springs are different sizes but equal size across from each other. This probably is to involve more springs to dampen the effect of increased torque. I'm going to try a machinist friend to see if his company can manufacture a new spring. Unless you know someone who sells these springs. My torus cover neck looks great on the inside, but has a small groove on the outside. The new oil seal seals tight though
