Gonna update this, since I'm experiencing the same issue. I have Spohn uppers and lowers, all are stock replacements just as the Gbody. Spohn told me that the cross brace can be spun around if needed. Now that I look at it, this should do the trick, requiring minimal spacers. I'm sure this is common, they could have included instructions to point this out for regal owners. Kinda ticked off about this.
