I purchased a 1998 gmc savana 1500 explorer conversion van. I want to swap out the axles to convert to 6 lug to use the wheels that I already have. Has anyone done this? Will truck/yukon/tahoe/suburban axles work. I believe that my diff is the 8.5 10 bolt.....same as my 1997 yukon. I also believe that they are all 30 spline but it comes down to the length... Any info would be great!
