My advice, rebuild the one you have. Any used one will have the stay-arm issue unless it has already been dealt with, which you won't know. If that tcase has over 160k miles on it then the stay-arm is going to be a problem. It's not really a hard fix and does not take much in the line of special tools.
As for the "new" one, it should fit. Take off the transmission adaptor first though, obviously. I do see the drain plugs in the first picture of it. I cannot read the numbers in this photo and am not sure what holes you are talking about.
Edit: One thing I cannot see in the picture either is the speedo sensor hole in the tail housing. Is that case off a 92-96? I believe they changed that part, since they do not have a speedo cable.
