I have a 97 2wd B2500 conversion van that I want to have converted to 4X4. I do not have the facilities, tools or skill to do this job. I am located in Columbia, Sc and am looking for recommended shops to do the job. I don't mind travelling to drop it off or shipping it if necessary. The main requirement, is that it be absolutely roadworthy after the conversion. I am retiring soon and want to be able to travel and explore this great country. Any assistance is appreciated.
