Window regulator

[Grumpy old man]

I have a few dozen used regulators and some extra springs , there is not that much tension on them and you should easily be able to wind one back in place with caution as with any spring under pressure place a rag over it to prevent it from shooting across the shop , the trick would be to count the rotations when removing the old one from static position to compressed ,Pm me an address and I'll ship you one for free .
