I think it's a 9.5" ring gear. It's the other common toyota ring gear besides the 8". I've been looking at a lot of info on 80 series axles lately. Good thing you went with 17" wheels too. You should have no problem clearing those huge brakes! 
yeah thats probly what size it is. I was thinking a long time ahead when i bought the 17" wheels, cuz i knew that someday i wanted to swap to 80 series junk.
I just ordered my other pair of fox 2.0 air shocks off of ebay. got em brand new for 430 shipped, pretty good price!
