[REQUEST] Different "Showthread" template based on forumid

[Rose]

Hello all!

I am requesting something that should be rather simple, but I've not figured out how to do it. I'm wanting threads in a certain forum to look different than other forums. I've installed [profile]Firefly[/profile]'s "Change Style of First Post" hack which is doing most of what I need to be done. This hack calls a separate template "postbit_first" for all threads in the forum I specified.

(note - Yes, I know this hack applies to only the first post in the thread, but I don't imagine any threads will be longer than one post, so it works)

What I would like to do is call a separate showthread template based on forumid.

I looked into editing FIrefly's hack to make it work myself, but I don't think I quite understand how to do it alone.
