Thats not 100% true, look at the pic of Rorys diff http://www.gmh-toran...pic=14036&st=75I'm not saying to do either. The question was asked about the rear track if Commodore rims were used on a Skyline diff which was adapted to be used in an LH - UC Torana. Whatever method is used, the track change will be the same. The distance from the bolt up face on the diff to the outside edge of the axle flange is the same no matter which B/W axle is used. Also, the Commodore and Skyline rear discs are the same thickness where they bolt up to the axle. This means the distance from disc to disc will be the same whether you use Commodore or Skyline discs or axles.
I personally wouldn't use an axle that has been welded. Other people are more than hapy to use them.
Between the axle flange on the housing and the disc itself on my borg warner-commodore brake setup-plus one other commodore borg warner diff I have here, they have a spacer between the flange and the disc, ive seen a few commodore diffs with this spacer, but not on the skyline diff-i'll try and get a pic of my diff later

Actually here look at the bottom left pic of this diff on ebay see the gap between the backing plate and the disc??? you can just see the edge of the "spacer" also see how far away the disc is from the axle flange compared to Rory's diff
