Similar Shaft Recommendations

The shaft on my 3 iron broke during a round last week and am trying to get it reshafted, but can’t find the same shaft on the secondary market. It is a Mizuno MP Fli-Hi 21 degree, with a 90g Stiff Fujikura Orochi shaft. It’s an older line of shafts, that was mizuno specific, so I’m not surprised I can’t find it, but if anyone knows a similar profile shaft that would help a lot. It was my safety club off the tee, and not having that club has made my rounds a little harder than I would like.
