Is the tranny from a 2wd or 4wd vehicle? If its from a 2wd vehicle you won't be able to use it. You need a 4wd tranny. Also a t-case from a Dodge would have a right hand side output, you need a left hand side output to match your D30. So you would either need to swap in a front diff from a Dodge or do some homework on how to mate a Dodge tranny to a Chev/Jeep t-case. Probably wouldn't be hard, just swap input shafts but you would need to buy two t-cases.
Also a Dodge 360 is NOT the same as an AMC 360 and will not bolt to an AMC tranny(even if it is a 727, case is different).
