Speedy,

The clips have been engineered to be a bit stiffer than the originals, but they will just snap on like the originals as well as sliding over too.

Yes they are being made in house!

For now, we're just making the top piece as we can't keep those on the shelf here. When the side pieces become scarce we'll probably start making those as well.

Next will probably be the clear side markers since they're impossible to get for the time being...

We appreciate all of the input as well!

Thanks!
