its not done yet, working on it right now, but the lower bars are directly under the frame rails, and the uppers will triangulate pointing towards the front. Now between the frame rails is 30" and if you look at the axle you see a line and raised area that whole area is where the pumpkin is and cannot be welded to. Now you make wonder where the upper bars are going to go, well the will rest right above the lower bars, the frame is high enough where it's laid out the links won't hit the frame and the link mount will double as a bumpstop area. Kind of hard to explain, but I'm sure you understand.

A bag on bar set-up is plenty sufficient assuming that you build it to be. The 4-link doesn't care if the bage are on the bars or not. And honestly, seeing that you are trying to keep 700+hp under control, I really would suggest that you steer clear of a sleeve bug, unless you actually leverage the rearend against the bag. If the rearend moves an inch, the bag will move 1 1/2". That way you can raise the spring-rate while still using a sleeve bag. The problem is that you are limiting yourself to the amount of travel that you can get.

I think that if I were in your position, I would build the bag mounts into the upper bars. The bars can be designed to accomodate that with little trouble and should still fit under the frame.

hmm, I'm going to have to think about this, I really want a clean setup, no crazy tube work and such, and with not much room to play this is going to be tougher than I thought. Thanks for all the insight, really opened my eyes. Sucks I can't run shockwaves (theyre so simple and such a clean setup) but oh well.

It wouldn't need to be that crazy to mount the bag to the upper bars. I am not a fan of crazy tube work either.
