Is the transfer case for a 1985 blazer Tahoe 2.8L 4x4 compatible with the 1990 gmc jimmy s15 4.3L 4x4?

if they are both automatics then mabey. check the tag on the back of the t-case. the 90 is an NP231c. the 85 might be an NP207c. which is the older version of the 231 but not as desirable. if 1 is a stick and the other auto i think the spline counts are different
