Exterior Door Handle Gasket

I took my door handle apart to clean out the lock because it was being grouchy and noticed the gasket that surrounds the handle had a big chunk missing out of the bottom. I’m trying to source some replacements but I figure cutting out some new ones out of a gasket sheet may be the only way to go. Anyone ever seen any of those handle seals online anywhere? Thanks!

I have the excact same problem on 1 of mine… Have tried looking around, but had no luck so far finding those gaskets

I have a set they need to be cleaned but still good
