overall width

[Locky]

If i was to use a sierra donor it would be standard with the book, but if i was to use an omega donor then im fairly certain the car is wider.
will it look odd as the wishbones will be wider, or will i be better off modifying shafts to bring the overall width of the car in.
Still in the planning stage of things and getting things on paper. so some odd questions to come.
thanks,
Locky
