The reason I ask if you have to use the TT diff is because I'm going to be putting the RCM Slipperential in my Caster truggy so I'll have the stock Caster center diff already that I'd like to use instead of buying the TT one.

EDIT: I decided I wanted to make things easier on myself so I ordered the Thunder Tiger parts. Maybe the Caster diff will work, but I'm going to have a hard enough time following the directions with all the correct parts, let alone trying to modify it for different parts. I might be PM'ing with some questions once I start the build if that's alright with you mistercrash.

For anyone else interested in building the hybrid center diff: Total cost shipped for all parts came to about $50 (I ordered two of the plastic Revo gears in case I mess one up or shred it while driving). You'd expect to pay close to that for any other decent buggy/truggy diff so it's not too expensive IMO.
