The large coil spring on the door glass window regulator has broken.
As I'm reassembling the car, it would be nice to replace the broken spring but I don't think it will be easy to find a replacement, as these were Aust only.

Has anyone had any experience finding a replacement?

I don't know how long the spring has been broken and considering it seems to be mostly for counter-balancing, it may not be "vital" to the car.

Bill, how about a complete regulator?

David, are you offering?

Yes. I expected that a complete regulator would be the most likely fix but still a rare item either way.
The broken spring is on the right hand door, however the springs look to be interchangeable.

Yes, Bill, whatever way you want.
