Kerry, they are overall somewhat similar to certain T34 tracks but with a unique ridge pattern. At the site that Ales linked to in his posting they have some Shermam Cast Steel Tracks. In comparing them to the Dragon tracks they appear to have an almost identical tread pattern. See below.
Here's an "in progress" shot of my attempt to get the Dragon tracks to sit right after filing the teeth and opening up the holes.
I believe that I spent more time trying to get the treads on than it took to put the entire suspension together. One other trick to those that try to built this kit is leave the drive sprocket unglued. The Dragon tracks don't stretch much and it might be impossible (or extremely difficult) to get them on a completed suspension.

Regard,
Jan
