at a minimum, you have an 1988 Izzy trunnion and bolt carrier. FSB looks like a Saiga to me, unless it was modified.
Bolt should have some #'s on it too maybe. I know my bulgarians do. How about pics of the gas block and FSB?
To be honest, those who will be most impressed with your rifle being an 88 Izzy will be purists. I kinda dig your rifle though.
Good luck.
