Hi
These 4 windows will raise and lower but will not say up. The twist locks on the bottom are broken. I am unable to get the parts out of the groove and the trim seems to be made whole , I do not see any seems to take trim apart. I would need 4 pairs to fix these bay windows. Others in the house have different type hardware and try to fix these 4 bay windows first. No numbers, name or markings are visible.
Thank you for any help
Robert
