Source for AFU4600 fuse panel access bolt

Has anyone identified a source for the quick assembly bolt that secures the fuse panel in place above the driver’s feet? The plastic bolt that is cut down the two opposing sides.
Part number appears to be AFU4600
Usual suspects Rimmers/Moss NLA

I use Dutz 1/4 turn fasteners. A little ingenuity & “informed measurements”, they come in a number of lengths & once fitted correctly, so much easier.

I went through the process of putting Two in the basket and entering the UK address. At £22+ I think I might try a different option.
Not sure what that will be yet but a standard nut nd bolt has appeal!
Even a plastic one with the sides relived might become a suitable project.

But thanks to Roverlike for the links.
