monty sport front driveshaft

Hey guys, been too long since I've posted here. Sold my MM about 18 months ago and just bought a 2002 Montero Sport xls this week. What a fantastic rig! I'd forgotten how well built mitsus are! I have a simple question-it's missing the front driveshaft. I found a similar monty at the boneyard, but it's parttime four wheel drive and my monty has AWD. Does anyone know if the front driveshafts are interchangeable? I just don't have enough experience with them to know how different the t-cases are in dimensions etc...thanks
