I have a very nice 97 Chevy 1/2 4x4 pickup that I would like to convert to have 1 ton running gear. I've done a lot of work with old 80s solid axle truck but never anything with IFS, so I have a lot of questions for anyone that knows. First, is there even a difference between the 6 and 8 lug 4x4 IFS other than the lug hub, half shafts, spindel, or A arms. Is the differential itself the same between 1/2 3/4 and one ton (same carrior, ring size) or is it altogether different. Second, is the only difference between the dually 4x4 and single wheel 4x4 front end that 5 inch spacer behind the wheel. Can that spacer be removed to be like a single wheel front end. Third, I know that a dual rearend is narrower than a single rearend, but does anyone know if there are wheel spacers available to cover the distance so a dual rearend can be used as a single.(I ask because I found a dually parts truck for a great price) These are probably dumb questions, but this is the first truck like this that I've delt with and I just don't know much about it, plus its kind of hard to find any info on it. If anyone can answer any of these questions or send me a link to another site that may have more information I would really appreceate it. Thanks a lot.
