you do the pan the same as on a front drive car, except you leave the drive shaft exposed, atleast at a point where it drops lower than your pan which will be tucked up higher. i have a 1990 f150 4x4 have not panned it but looking at it you will need to leave a cutout for the transfer case also,, i would use self tapping sheet metal screws with big fender washers on the frame rails. watch your brake and fuel lines. those big rear leaf springs are another thing that cant be covered,you have alot of pattern cutting to do, but if you do it right, it could make a noticeable difference especialy if you combine it with grill block,mirror reduction or delete, but you also probably know that the rear is where the biggest gains are hiding, (aerocap,,,etc)
