K0422-882 shaft vs K0422-582 shaft

I have a stock K0422-882 that came out of my 2006 Speed6. I rebuilt it, and when torquing down the shaft nut managed to break the end off. I was looking to sell it but obviously this needs to be replaced. I couldn't find a shaft for the K0422-882, but did find several for the K0422-582 that is employed in the CX-7. Does anyone know if these items are compatible? The images appear to be the same, but I wasn't sure if there is any size differences between the two
