Just set up a group buy on their rear disk conversions for 1997-2004 dakota & Durango.
Kit clears a 15" wheel and will work on 8.25 or 9.25 rears.
Full kit with calipers (with E brake!, cable extensions included), pads, rotors, mounting brackets, and 8" stainless steel brake lines is $660
The deal is if we order only 3 sets we get 20% off
So full rear disk swap for $528 (before tax & shipping)
$348 if you decide to use none E brake calipers.
$+80 for dimpled and slotted rotors.
Here is their website. I've been doing research on these for days now and even guys running 38" swamp tires are happy with the power of the single caliber brake set up. From what I hear they use stock front dakota rotors and calipers from 1979-1985 Cadillac eldorado so rebuild parts are easily available for years to come.
