Just throwing out there, the Quadratrac is a great t-case, just gets a bad rapp due to poor service. As long as the chain is kept within spec and you use the proper fluid for it, it is a fantastic case. They normally come as full time 4wd, offer low-range capability if equipped, and you can also purchase a part-time 2wd kit for it. Just throwin that out there for you. BTW, I run a built 304 (although now having some issues with it) on 38.5 TSL SX's and have not a problem with the t-case. Also running the stock t400 with a shift kit.
