1936 Terraplane window regulator spring

Rocket

could someone tell me is the main spring on my 36 Terraplane front window regulator is one year only or will it fit other years it is a strange looking spring and I think it is the same spring that is used on the back window regulators to but I am not sure I am going to have new ones made that is why I am asking any help would be great Tom.

If, it's the connected twin clock spring  I may have one. It was used on regulators up until the late 30's up to the 40's. I believe the diameters changed on different models.
