yes you do have heavy washers on the lolipop LCA bushings...
look at you photo of the left (driver's side) control arm

first you need to cut off the threads beyond the nut, they will hit the aluminum on that side
that bushing has, in order, nut, heavy washer, funky rubber washer, bushing, funky rubber washer, heavy metal washer, control arm.
If you don't use that washer it moves the control arm bushing forward a 1/16 or so. My arms required that washer to be removed or it just didn't fit in the forward LCA bracket... on both sides
I tried and never got a dimension from F5 re exactly where the ball joint should be... Everyone else that I communicated with was right around where my arms came out... I'm keeping my fingers crossed re body position. I can at least assure myself that they are in the same place side to side. I disagree as to the conclusion of how to fix it...
left, clip the vertical bracket a wee bit 1/4 should do it, I did about 1/2, twas too much. You may need to elongate the hole towards the rear a bit on the upper metal bracket, the lower bracket should work fine
right, you may need to elongate the aluminum lolipop's hole a wee bit, mine was between 1/4 and 3/8 of an inch. The lower should be fine. Some had to clip the vertical section of the upper bracket, again 1/4 or so to get them to fit.
Since you are using the front pivot as fixtured and the two lower rear lolipop holes, we all are placing our lower ball joints in the same place. there is some "slop" in the hioles and you can make them as even as possible when you verify their position relative to each other with a straight edge or broom stick
I'l measure my exact wheelbase soon and confirm. The rear suspension placement is non adjustable when you use the stock trailing arm.
