4x4 conversion???

[gmc71]

Hey 4x4s I'd like to move over to this board full time but first I need the truck, do you think you can help?

I have a 71 GMC LWB 2wd. How do I go about making her into a 4x4. I have inspected the frames on some 4x4s and believe they are essentially the same.

1. First I would have to scrap the front end and make room for the leaf springs (bolt on) and front axle(dana44).
2. Then and put in a crossmember for the transfer case.
3. Hook up the new drive shafts, and I'm off to the bogs....right, or no its not that easy....

Please explain, or post some helpful tips..... or email me at: bdheeter@adelphia.net

Thanks
