Could bolt on thick angle iron with two holes. Should slide spacer between LCA where you drill the hole so you can bolt it across the LCA. Sort of like the shock.
Should not be a big deal for a muffler shop to weld those Hotchkis sway bar tabs though.
Would be nice to get some bigger tires if you are interested in handling. Like 225/60/14. Or on a budget jump to some 15x7 cop rims and 225/60/15 tires.
