True, there is a slight difference, on a couple of the pics, but I at no point have advocated that he buy them, just commenting on what I had missed initially.
Addit: Am I imagining things or did at least one of the photos in that link, with wheel not on the car have the RR on a spoke when first posted?
If your wheel has been welded well it should be as strong if not stronger than the others. 22 inch rims on a fullfat often split due to vehicle weight and the amount of flex created in the rim by the smallest of pot holes.
