I know this is a bit off topic for a 73-87 chevy truck group, but was hoping someone might have an answer for me...I am wondering how difficult it would be to covert a 2WD Task Force series chevy pickup to 4WD by swapping out the front and rear axles for 4WD units, adding a transfer case and making adjustments to the steering as necessary. I know the Napco units were bolt in, so I am wondering how difficult this would be...Any comments appreciated. Thanks.
