Thank you for contacting us. I see that you linked to a discussion that regarded our Series 170 coil spring. Is that the same Series you have? If so, how about our S170-407?

If you aren't certain that this is what you have, please send a few pictures of your hardware for us to look at. I'd like to see a picture of both the pivot shoe and coil spring. Thanks!

Do you have this spring, if so I need 2.

Thanks for getting back to us. These pictures are a big help. I think the Series 170 is a great place to start with this spring.
