Please forgive my ignorance, and lord knows, don’t do this till the smart one’s chime in. *That is not me. *
I say put a third brace on the lower “A” arms about mid point, rotate the tab on the third, newly installed brace on the lower “A” arm (That seems smart bdkw1). *(Looking at the rear shot, the new cross brace may not be required as it might get the shock beyond 90 degrees at full compression?). *
Then run a cross brace at approximately 45 degrees from the rear most vertical tube to the horizontal cross member that appears to be 12” from the rear most bar. *The shock mount point would then intersect at the approximate mid point of that newly mounted 45 degree cross member? * Seems that way it would all be braced together and allow for possible front to rear mounting alignment so optimal placement could be reached? *
Again, WAIT FOR THE SMART ONES! *I am just throwing this out as an idea. *
Smart ones, feel free to pounce on me and toss me back into my hole. *This thing here -->>
