Milestone hardware

Looking for replacement parts for a aluminum window,company was called "florida extruder international inc. Think they went out of business, sticker on window says Window model Milestone single hung series 2000 Tried sending a photo I took but had trouble uploading it, can try again if u need me to. Let me know, I saw a picture on website of someone who had the same company "milestone" that you found for them but look liked it wss a different series window, please advise Thank you Jason
