EDIT: a comment from facebook informed me that I may have an 8 lug axle, which is also narrower the 6 lug, this is something i did not consider. i was almost certain this came from a 6 lug though
I feel I have been bamboozled. When I went junkyard searching for a 14b SF axle, I knew one of the most important things was I needed to get it from a 4x4. the truck I pulled it from was a 99 k2500, I verified it was 4x4 due to the fact it had a 9.25 front diff which I had contemplated taking as well until I found out it is not a direct bolt in swap. It was just the axle housing so I need to buy new axle shafts, the yukon shafts below is what I bought ( I would not buy from them at those prices, way cheaper elsewhere online).
they finally arrived the other day and when I went to test fit things together, the axle shaft bearing surface was poking out past the seal quite a bit at least 2 inches it seemed. I knew something was up, I tried referencing videos an pictures on the web and found nothing that looked like this. I mocked up the disk drum and it was at least an inch away from the backing plate.
I measured spring perch distance, it was about 47", about the same distance on my 4x4 tahoe. tip to tip of the 14 bolt axle I have is roughly 63", hard to get accurate measurement with the backing plate on one side. one side of my brain is telling me you have a 4x2 axle and those are 4x4 shafts, the other side is telling me I know I got this out of a 4x4 truck something is wrong about the axles.
Either way its going to be a mistake that is going to cost several hundred dollars to fix. hoping its the axles as that is just money vs the time and money of finding a new housing, getting it blasted and coated and buying a new bearings and races( not sure if they should be reused once that have been pushed in even though they are new

I did find this axle when i searched replacement parts for 99-00 carryover model, this is clearly labeled for a c2500 though. If this shaft does fit and I do indeed have a 4x2 axle, would a wider rear wheel and tire make up for the shorter axle width

and on a final note, it looks like I will either have 2 brand new axle shafts for sale or a fully prepped 4x2 axle housing for sale, has new bearings, seals, races, new vent stem, and blasted and powder coated
