Looking for old/used Kangertec single coils for Aero 2 tank, for rebuilding.

[pierssy]

Hello everyone, I am a bit of a dinosaur and a skinflint. I use a Coolfire four with an Aerotank 2. I make coils and rebuild. I only have 4 coils and the rubbers/silicon bits are giving up. I wonder if anyone has a cache of these, used but with plenty of rebuild life in them? I am looking for a freebie really, but I can pay for postage via PayPal.
Thanks for reading.
