I put one in an 05 frame with a similar lack of room, but I think it still has more room than the older bikes
Dang..thanks for posting this man!!
I looked around pretty hard on the web for someone who had put a dropper in one of these old interrupted seat tube frames.
Your 05 is the closest/only one I've seen, makes me more confident that it can/will work.
Nice bike by the way!
