Hello,
Unforutnately, our tie bar guides are not available in metal. We do offer the 39-448 if you'd like to try a different style but I'd also like to get a bit more information from you to determine why this may be happening. In general, these guides should last longer than a year and are not under a lot of pressure. If you could show us an original guide from one of your windows, as well as a broken 39-417 replacement, we can go from there. It would also help to see a photo of one of the 39-417 guides that is still installed. Thank you.
