Got a replacement from Gerber for my broken M400… not what I expected. Can I get replacement blades for my old style M400?

I’ve used and abused my trusty Gerber M400 for years. I learned recently that I can use the warranty to get a replacement after breaking a couple of blades. Gerber sent me the new M400 (I guess) on the bottom.
Is there a supplier I can contact to order old style knife blades and screw driver blades?
