A very expensive and dumb mistake

[Ole Buck]

finally mocking up the drivetrain after setting the engine transmission and transfer case and then I saw it. I guess I just got excited about doing a one ton swap into my 87 square and just simply bought the wrong rear end. I already have 5.13 gears, arb air locker and disc brakes.the spring pads have been cut, moved and welded to fit my truck and it will not fit. I am sickened. I want to throw up. I am off the complete width of my driveshaft. This rear end is offset and not centered like I need. Will someone please tell me exactly what 8 lug full or semi float that I need to make this work please.
Here is a picture of my bowl remover.

Why not just try running it? I can't think of what they were off hand, but I know there have been factory built trucks with an offset pumpkin.

It would be way off center. This rear came out of a 03 2500 I believe. The yoke and pinion are off set instead of centered like I need. I don’t know what I was thinking. I had no idea it was like this.
