What SWAY BAR to choose

I'm in the same situation. Biscuit mount K member with 73-76 control arms. I asked Helwig and they recommended the #5904 for my Duster.

I’m running the same situation but with the rear mount calipers (spindles swapped side to side), I am told front mounts interfere with the 67-72 sway bar.
