Injectors wanted for D2 4.2

[Paulg390]

Sadly my 1998 S8 has developed an intermittent misfire after standing when warm (heat soak related). It looks as though it is an injector as had them all tested and 2 had impedance slightly out of tolerance. Once put back in only one now seems to be giving an issue and the fault code chases that injector if It get moved from cylinder to cylinder. So I am looking to try and replace one or preferably both the injectors but A8 parts don't have any in stock. Don't suppose anyone on here as some spares laying about... ?
The part number is 077133551 L , apparently the L is important.
