How good is the Haynes IRS?

Is the Stylus like the Fury ie same track width? If so you are into chopping down the drive shafts as the Roadster uses them as per the sierra.

thanks for that, i did wonder if the stock shafts would be wider, i think i can get the shafts shortened, or new ones made but its an expense i could do with out. I was wondering whether an MX5 diff and shafts would be the right size. Of course that means using MX5 based uprights. I will have to look up some measurements.
