Transfer case ?s

[milner]

I a looking at a NP241 transfer case out of a 91 burb. I was wondering what to look for when checking it out. It is out of the truck, he had it in a 84 but sold the truck and kept the t-case. Is $75 for the case, adapter and crossmember a good deal? He said it worked when he took it out of the truck. Thanks in advance.
