Will I have any problems using a D44 from a 1978 Jeep Cherokee for a future SAS project?

I know of a family friend in San Antonio who had the Jeep sitting at his house for 5 years with a broken motor. I finally ran into him at an HEB and I asked him about the diff. He told me that the front diff was working great before he blew the engine and that he had even put manual hubs on it. He is asking for 90.00 for the front diff with the steering linkage.

Even though my SAS is still sometime away IÆm thinking of purchasing the diff because I think itÆs a good price.

Let me know what you guys think.
