I'm not sure what you want but IF its the "insert" that goes into your division bar the "insert" is available.
If its the piece that the "catch" for the wing vent handle catches on then I am not aware of any repops.
I just did my 52 which are probably like yours. I'm looking for the little "insert" or vertical division bar that the side window slides up in next to the vent window that has the little chrome "beads' on each side. The new ones I bought are solid black.
The handles, rubber pieces, rivets ect are all available from most vendors. Even complete vent assemblies but they are high dollar.
If this don't help can you be more specific? Its Wednesday and I don't do well on Wednesdays
