3rd gen Dakota? 97-00 (or 01) ?
There was a Dakota RT available in 97 that came with a 5.9 option. I'd probably just use the front springs for them. The early Durango 97- 2000 or 2001 were based on a Dakota chassis, so those front springs should work as well. I would also suspect the 03 (or 04) and newer Durango and Dakota probably shared the same chassis and probably used the same springs. My background is in the 88-96 Dakota era. Gene
