I have a set paid for, waiting shipment and I found a set of cheap used Jeep Rubicon takeoffs that are tall and narrow. So I am thinking of running them on my '89 Gen 2 (same as your 4 Runner) pickup... My only worry was that it made the truck track width narrower than it is stock, but looking at it with the 4.5 backspacing it should actually be OK I think...
