Lock tumblers / wafers wanted or old lock with no key

[Hampole]

Hi,

I'm rekeying an ignition barrel to fit my key. All has gone well and I'm at the stage of swaping the tumblers around to fit my key. This has gone fairly well, but luck is not on my side though as I will need two tumblers to make all of them work.

Does anyone have a selection of tumblers I could buy, or alternatively an old lock that they have lost the key from.

Thanks
