Looking for replacement bayonet mount ring/hood

The flange on the bayonet mount ring (actually more of cylindrical or hood-like part in this case) of my Nikon telephoto lens AF-P DX Nikkor 70-300mm 1:4.5-6.3G ED is broken. From looking at repair videos of other similar Nikon telephoto lenses, it looks fairly simple to repair myself, however, I have so far only been able to find a replacement part on AliExpress, which I have no experience with. Ebay continues not to offer the part. Nikon Parts does not. Any suggestions where else to look?
