Hi and welcome, shame about your transom wheel, I assume you mean the leg and wheel? It's a long shot that someone may have the odd transom wheel, but which one - left or right?
If you don't manage to get one, I wouldn't get another set of the Excel style wheels, they are not the best. I'd advise you to research transom wheels thoroughly (loads of threads on here) they where the bain of my life!
