insane wayne

So I've been doing some rust repair/prevention on my S14 and pulled the fuel tank to get access to some otherwise inaccessible areas. On the fuel tank protector (gavanized steel piece that sits between the tank and the subframe) there are these little metal clips that snap onto plastic 'buttons' on the fuel tank. Several of these were too rusted to remove without breaking, and now as I prepare to reassemble things, I am left without a way to mount the protector panel . All the parts sources I've checked show these clips as part of the Fuel Cell Protector, and as far as I can tell, you can't get them by themselves. Does anyone know of a source or alternative for these?
