I notice the rectangle has a longer “stick” on the opposite side. I hope this is only to keep the rectangle in place. If so, you could flip the rectangle (and keep it in place with glue perhaps?) and trim the longer stick to a good ratchet length.
I may have it all wrong as it is hard to follow exactly what is going on.
Failing everything else, i would buy a thick enough piece of styrene (or 2 thinner ones for easier cutting and glue them) and recreate the rectangle with longer nubs. It is tough stuff. A stanley knife (or even dremel for the tricky bits) should be all you need and a sheet of styrene will give you many attempts.

Styrene is not a bad idea. Get the same thickness (depth) as the piece you’re mimicing. You can always make a stronger rachet that way, by altering the thickness of the piece you’re trying to replace. Only problem is that you will likely end up with way more styrene than you need.
