Any idea what these things are? Found inside front window.

Sitting at the bottom. About 2cm / 3/4” rubber plugs with hole on one side.

Thank you

Bumpers on the electric window regulator?

Yes, those are broken window buffer stop rubber from the stop bolts. Still available new https://www.wallothnesch.com/en/catalogsearch/result/?order=name&dir=asc&q=window+buffer

On late 73 and all 74s the stops are on the regulator itself and have no rubber.
