The front 5.83 is still available, as far as I know, from Calmini, it's the rears that are hard to get.
I can think of 2 options, get 5.38 sammy gears and change your rear carrier to a sammy one, the front
of a kick is the same gear size, or the new reducer box that TT or someone has out now that goes between the trans and t-case.
Other than that, keep looking for the rare 1.3 88-89 Sidekick, that's where the 5.62s live
