Kar98AZ Help

Guys, I found a lowly Kar98az barreled receiver at the Phoenix SAR show 2-3 years back. Out of China and in a pile of beat to death Chang kai shek Mausers. Only barreled receivers, all with bad bores. I need the middle barrel band SCREW. Only the screw. Not locating one anywhere. Does anyone know of any in Europe/Canada. I am not seeing Kar98az stuff, even bolts are hard to find. Thank you . Again, HELP.

Back when I was restoring mine, Polish parts were still available. You might try that route. Even if not currently available, ebay might get one on.
