I have a 98 or 00 (bought off of a guy door says 98 owners card says 00) Durango SLT. I heard the SLT had an EVIc, dual climate control, radio controls on the steering wheel, and heated rear view and side mirrors. I want to add these. I owned Rams and the wiring was all there, is the Durango's like that? Also what years did it have a straight axle? Mine has IFS so how hard is it to do a SAS swap?
