Link setup Question

I'm not bashing this setup, but what could this guy do to make this a more efficent setup? We have tried to give advice with no such luck, so I am curious as to what some of you guys would do. Mainly referring to the mounting point on the wishbone.  

A crossmember that continued to the other side of the frame would be nice.

agreed...that mount is just waiting to tear a big hole in the frame.  Some sort of crossmember going all the way over would be the safest bet...
