You’ll want to leave the factory A-arm bolt, inner washers, and bushing sleeves in place during welding to keep things from moving as you weld. To make access easier, the inner washers were stacked against the gussets instead of remaining in their usual locations. It’s the total distance that’s important here, not the position of the inner washers. Weld everywhere you can reach on both sides of the gussets. The vertical welds down the coilover buckets were the most difficult.
