NO!! Yo must retain at least one upper to control the rotational forces on the axle....Set ups like Claytons are a radius are. There are only 2 main "links" but they attatch at the vertically seperated points in order to control rotational forces.
I hate to say it frankly, please don't be offended, but from the pics you have posted there are many problems with you current set up. You would be money and time ahead to use a proven kit like Claytons, tnt customs, RE, Tera etc. Suspension is not something you want to mess with if you don't fully understand the forces at play....You could end up with something VERY dangerous.
