question about lifting a swb 6inch

[coggonobrien]

ok the plan is to lift my 68 swb when I convert to 4x4. I am thinking a 6inch alls spring lift with 37 inch tires. I will be using a 75 3/4 for the 4x4 hardware. What all do I need to do have a sucessful conversion that will last and be safe. I know I need to reorient the angle of the rear axle housing, should the front be done? I know I will need to modify the break lines, how about steering components? Also I have seen trucks with support bars running from the axle housing to the frame, should I make them? any other suggesionts would be great.

Thanks,
David
