Supposedly there's about 150k on it. Should be a good basis for a rebuild.$150 is a great price for the T case and shaft. Try to find out how many miles are on it?
The AWD T case on the Gen 1's was kind of a rare thing. Most of the ones I found along the way were the part time 133 or 233. As we know, the R/T ('00-03) came standard w AWD, so those are a good source for them.
Wouldn't hurt to bang a new U joint into the shaft but I'm not sure if my funds will allow it just yet.
