Parrallel Upper Rear Links

[Harvo]

I have seen Axials on here with parrallel uppers and triangulated lowers... and others with both uppers and lowers relatively parrallel.

I would think that if the uppers are parrallel the lowers would have to be triangulated, but several of you seem to have success running both uppers and lowers relatively straight back.

Does your axle have a lot of side to side movement that way?

I have a dig servo on the rear axle. I want to 4 link it by using TLT link mounts on a wide servo plate. They would have to be parrallel to make it work, but my lowers are almost parrallel now. Would I have to move them in at the skid to make it work?

Thanks
