Merry Christmas <img src="/forums/images/graemlins/patriot.gif" alt="" /> and thank you for your service!

Sounds like you're going to use a stock 12" long TJ coil....much like Napolean did. So I assume your shackles are about 3" longer than stock? My gut feeling says the "Napo coil" will about work for you(see pic below)....you might have a little more lift but you can reduce it by putting stock shackles back on. Now the thing that bothers me is the TJ coil is about 6.5" in diameter....so it comes closer to the tire than my skinny red coils. But that might only be a concern with wider 12.5" tires. This would be more of a concern on 85 and older rigs with the narrower housing....the 86 and newer ones are 3" wider. The Napo coil is not self capturing but heck, most people wouldn't mind that in a DD kind of Runner. Sometimes you can get the coil for free if you know somebody. EDIT::::In your configuration, this would mean a softer ride....yes, your leafs will likely never sag ....and payload goes up. Not bad.
