window regulator spring question

[Doug in NJ]

Hello,

On the two-arm regulator (used in the S/W front doors), there is a big spring and a smaller spring. The big spring looks like the single spring used in the rear door's single-arm regulator, but it is about half a turn longer.
Does anybody know of either of these S/W springs are equivalent to the springs in the single-arm regulators used by the non-slant cars?

The big spring in my driver's door regulator is busted, and I am wondering if it can be replaced with the repro spring that the vendors sell, or if I have to find an original S/W front window spring.

Thanks,

Doug

Here's a photo of the larger front window regulator spring and the rear window regulator spring from my S/W sedan. (The larger one is for the front window.)

Is either one of these equivalent to the repro spring that vendors sell?
