Where to buy T5 shunted tombstone end caps?

[Delphinus]

Can any of them provide non-shunted? FWIW, I think shunted just means the terminals have a jumper wire which you can add yourself. (I always understood it to be as, non-shunted ballasts provide a wire to each terminal pin of the lamp; where shunted means you get one wire to the end, so for both pins to get current you put a little jumper wire in so both pins get attached to the same wire. I'm probably doing a bad job of explaining this, sorry ... )
