Maybe your panhard is bent or you need an adjustable one.
No the diff will not fit without modifications as stated above. Surely it would be easier to get a VL sedan diff and put that in. I have just fited a VL 3.08 28spline LSD to my VK sedan and it just bolted straight in, got to be easier than having to change all your diff mounts, or look for a swap maybe someone with the sedan diff you want will want your wagon one, or just change the internals over to a sedan housing, but thats not that easy to do with out some prior knowledge either.
Nope not bent at all and have tried an adjustable one too. The diff is a few mm wider than a VL sedan diff, a few mm shorter than a VN sedan diff. Wide buggers.
Also, its lowered so the tyre that should scrub would be the drivers side.
yeh its not for me as such but one of my dads work mates is building a group c replica and bought a v8 wagon lsd and the n discovered it didnt fit and was wondering if it was different diff or out of a different model and if i was to get it rewelded i would get the welder at work to weld it for me
