I recently found this  http://shop.akoperatorsunionlocal4774.com/Under-Folder-AK-to-M4-Stock-Adapter-Under-Folder-M4-Stock-Adapter.htm
I'm not sure if this will work with my M70AB2T Sporter hence my asking. I considered selling this gun then buying another but this leaves me with the option of having the underfolder kit in my bag since it's decently light and won't take much space compared to my bag should the stock break. If anyone has used this any information would be great.

Thank you

Yes, it should work. There's a drop-down box that gives you the option of a Yugo version.
