ImmtbikerYeah they should be able to bring up the old molds, they keep a copy of everyones molds so you don't have to get new ones every time. I was going to join the drop but it being "US Only" is a big disadvantage, I'm going to wait until the next drop.
To further answer your question I will quote the UE FAQ (Frequently Asked Questions) page "Q: Does Ultimate Ears Pro keep the ear impressions or send them back with the order?
A: We digitally scan all impressions and we keep the originals on file. We do not send back impressions. After two years, we advise you to get new ear impressions for proper future fit."
I already had molds done at UE for my UE10's. Can they still be found/used?
