Aluminum transom trim

[toadfish]

I removed the aluminum trim along the transom to check the condition of the transom and to put new sealer under the trim. It was stuck down pretty good so I had to get ugly with it, assuming I would just replace it with a new one. The transom looks good and I cleaned out the corrosion that was building under the trim, now I can't seem to find any replacement. Any suggenstions?? Its the trim that lines the transom notch and is only a few feet long.
