Pirate Jacks front disc kit question

The best way to fix the issue is to go to the 73-76 swaybar. Seeing as how you are well into rebuilding the front suspension best solution is to change the hardware. Shallow nut and shorter bolt should clear. Just remember that the hardware is the only thing holding the suspension together. Use grade 8
swapping to the 73~76 bar would also entail swapping out the K-member and lower control arms (and motor mounts).

short of cutting off the tabs and running an aftermarket bar with different pick up points the most practical way forward would be different nut/bolt set up.
