My 85 4Runner had 7" springs up front, and coils in the rear, and no body lift.
With this set up, I ran 35" Boggers with no rubbing at all. So I think if you put your 7" springs in there and did a shackle lift as well, you'd be OK.
But if you already have a 4" body lift, go with a 4" spring as well and you should be good.
