Hey there!
We should be able to help with this. Can you show us a photo of the pivot shoe, preferably removed from the window? Seeing that will allow us to determine the compatible springs and supports.
Thanks! That pivot shoe looks like a match for our 15-191. This is designed to be compatible with our 1/2" wide Series 160 spring and 15-150T triple spring cover. I believe these are what you want but look them over and let me know what you think.
As for the lock, we don't sell anything like this. It reminds me somewhat of our 90-281, or maybe even our 90-298, but yours doesn't have screw holes. I'm not sure how well these would work, if at all.
The cut out on your old spring is different but our Series 160 springs will still work. Your lock is very odd though; I'm afraid we don't sell a good match for it. Your best option may be to reach out to Milgard directly if you haven't already. I am very sorry for the inconvenience.
