I purchased a 2000 Dakota 4x4 Ext. Cab SLT at the end of Sept. and I knew it would need another Core put but I held off because, it was affecting me or anything at the time and I had other commitments at the time. Didn't count on old man winter rearing up his ugly head this early on this year. My question is: Since I'm not a mechanic, and if I were to replace the core myself, you'd have a hell of a time figuring out what it was that I did to get that Damned thing in backwards. Basically: I need to find a mechanic to do the job for me, what I need to know is ballpark estimated figure as to how much it'll cost for me to get it put in if I purchase the parts myself?
