About wishbone, I think some explaing is in order.
I'm thinking of dragstyle,not offroad full welded structure, here we have a simple capitol A with one extra tube coming straight down from to top of the letter and there is another free movement tube going out inside this tube and they make a kind of telescope structure. There is two connections at bottom ends of letter A and one on the end of inner tube. It will go shorter or/and longer with suspension movement. So it will never ever prevent it and nothing like ladders cos Wb not full weldet structure.
Exwestracer is right track with me here. Wb is problem free desing. It's more free than wattlink.
I calculatet that it can be fab it around rearaxle 8 diffrent position and ways and all they can be same as cars centerline (or what its call'd)
If you use Wb it will take all side to side forces of your suspension link tubes.
Again, I not saying that you all are wrong, just that there is easyer way to do it right.
This was the way I did it in my Swinger six years ago. I did welded some extra 1/4" plates after I bend it speeding way to fast in Estonias back roads.
