WotLK Old account

Hey, sorry if this is a stupid post, but if i had some boosts+ items from back when the server got wiped, could i get those items back? The characters that had the items aren't available anymore, but the store transactions are visible on the site. I don't even care about the instant 80 boost, but heirlooms+ glorenzelg were pretty nice.

Tldr: had toons boosted after wipe, want gear back

Any help would be appreciated.

Thank you :)
