Inserts for MEC adjustable charge bar

[Sooner]

Does anyone know where I can find the replacement key shaped inserts for a adjustable charge bar for a MEC? This is the aftermarket charge mat with adjustable lead and powder volumes. Not the MEC factory bar.
Thank you.

I'm fairly sure I used a standard MEC replacement on my adjustable bar.

Thank you. I’ll give that a try.
