IIRC, the angled arm help the overall geometry of the x-over. A steering block would only bring the drag link closer to the crossmember, which would hit as soon as you are crossed up.
I know that when you run the ORD X-over with ORD zero rates, even with the bent drag link, it will bind on a stock engine crossmemeber.
I would get the angled armand be done with it.
