Rossi 62sa parts

Does anyone know where I might be able to find this screw? Numrichs is out of pretty much every part for the rifle. Ebay and Gunbroker don't seem to have it. I still have to give Rossi a call but I don't have high hopes of them having it since they haven't produced the rifle in a while. Anyone know exactly what part I should ask for when I call Rossi? I wasn't too sure looking at the parts diagram at Numrich.

Looking at some pictures online I see that now. So I need to find a sideplate and a sideplate screw.

Well I just got off the phone with Rossi, give the guy the only visible number on the gun, he said it came up as a revolver so he couldn't order me any parts. Told me to call back later with the rifle in front of me.

Called Rossi back a second time. Looks like my rifle was brought in before they started doing their own importation. They have no parts and no information. They referred me to M&M Gunsmithing. I sent an email off to them inquiring about parts.
