all supra strut bars fit the LS...their totally interchangeable. i have a 91' LS with a carbon bar for an MKIV and its fits perfectly...i origionaly used a few washers since the egr vacuum lines knock but I removed mine eventually and it fits with no modification whatsoever. Mike at JIC watched in disbelief as I sized the bar (still in sealed plastic bag) as it fit over the struts.
