Very nice job! Good tip about the heat gun, I almost destroyed my panels ripping those things off. When I did this, I found it easier to cut the vinyl layer with a razor and it pulled right up. The adhesive for the vinyl was weaker than whatever unearthly crap they used for the inserts.
I think I like your method of making new inserts better than the balsa wood I used. More easy to trim than wood is
