I was looking at an early 70s (70-72) 3/4 ton GMC pickup that is lying in the woods behind my house, and it seems to have a full-floating front axle (probably a dana, from what I've heard), and I was wondering if this would fit in the front of my 78 /forums/images/graemlins/k5.gif? I know I would need a new u-joint for the front driveshaft, but would i have to do any modifications to the driveshaft? Is this worth the time and effort? I'm not sure if it is any good and I know it would need at least a rebuild. Thanks for any help, guys!
