That's what the spacers are for in the kit - to keep the bushings on the bar side lined up with the holes on the axle side.
With the ant-wrap up above the driveshaft I'm not concerned with dragging it on rocks so I don't think I need to add anything between the two tubes
The center gusset is not just for bashing strength. These bars see an incredible amount of force. If not designed properly they will bend up just from the rotational torque. I haven't heard of anyone bending one of Kert's backbone antiwrap systems but then again I haven't heard much feedback good or bad from owners of those. WFO Concepts also designs their bars with a heim and no center gusset though so maybe my design is just stupid overkill but I'm ok with that.
I have given Kerts anti wrap bar and backbone system a good test pretty much everytime the Maiden is driven
Dry pavement launches to drag races... No hop, no pushing movement of the rearend related to the bar system, just smooth acceleration

Mmmm, sexy. Ill never forget that getting dropped on my face during mockup 
I guess I can contribute to this thread as well. Built this out of some RuffStuff axle brackets, 4" shackle, 7/8 heim w/ a mis-alignment spacer, and a fabricator set from DIY. Built a simple cross-member that eventually tied together with a tranny cross-member/skid plate so it's all tied together and really strong. Also used leftover 2" HREW tubing for the main tubes and 1" tube for the bracing. Seems to work really well and was cheap
I have Kert's backbone installed and I was planning on using a heim similar to what truck-oholic used however I wasn't planning on plating the gap between the two tubes so the heim is functional. With the ant-wrap up above the driveshaft I'm not concerned with dragging it on rocks so I don't think I need to add anything between the two tubes
That depends on the location of the two joints on the axle. If they were near 180 degrees apart around the tube it would not be necessary as one would be in tension and one compression.
However, if one of them if halfway around then the axle, rotation can put a bending moment on that tube(or just move it if there is a heim at the other end), so you would want to at least add a link between the two like shown on Zim's rig.

Bringing this back up. I had a chance to play around with my suburban. I did put a anti wrap bar on it and im so impressed with the traction. I noticed when i accelerate the rig stays level and seems to load th front end. I was on gravel and the more i mashed the throttle the more it seemed to grip. And there was very minimal wheel spin
Yeah, Zim can launch hard enough to break the transmission case. Maybe the anti-wrap bar made it happen
Anybody else notice with an anti wrap offset to one side that it torques the vehicle side to side?
I think it has to do with the cage being tied to the frame, and the deeper gears, probably my soft 57" ford leaf springs.... As mine never did this last year.
But when I get on it on the road, the whole thing just torques all over when getting on or off the throttle. I know that Dave's is much more centered on the axle so I'm wondering if I need to build another on the other side of the dif...

I have the ultimate anti wrap bars and mine will do that. But it is because the air presure in the tires is off by 2 pounds from side to side. Took me while to figure than one out. When they are dead on, no issue.
I'll have to check that....

Yeah mine torques side to side. I wasnt sure if it was the Detroit or just big tires. And im sure my air pressure is off.
Since ive had litte time i wasn't sure where to pinpoint it. But it feels like the wrap bar

So do I.
Also, double check your rear u-bolts and center pins Adam, I broke a center pin once and didn't know it, caused the rear to want to pull to one side under power since the axle wasn't straight anymore.
