Alien trigger wire gauge

Busted the trigger wire on my yellow alien. Tried to fix with the BD trigger wire but it is too thick. Anyone out there know what gauge wire is used?

Also very dissapointed with Fixe's customer service, I emailed them twice with no reply.

Thanks!

There is a kit for that:

Rock & Snow (New Paltz) sells it.
