Wanted, 2003 E53 or earlier load cover support brackets in black

[Davrosbimmer]

I'm looking for a couple of black load cover support brackets, PN# is 51477033549 and 51477033550.
These go on the earlier load covers that kind of fold like a roman blind instead of the later roller blind type load covers.

Already been offered a pair or £40 including postage,  but think that's a but much for second hand ones.

Thanks for looking.
