Thanks for the good advice! I went to size up the strut tower bar with the one that's already on my car and I found out some pretty good info. For 1, the APC bar that's on the car now seems pretty rigid with the "pushup test". It seems just as stiff as the OEM GSR strut bar. 2nd, after removing the APC bar and sizing up the GSR bar, I realized that the GSR bar is too long/wide for a 1995 LS Sedan. There are 2 holes on the shock tower that have rubber plugs in them on the fender side of both shocks. I'm presuming that these are for the GSR's shocks, since the bar would line up perfectly with these holes but not with the sizing of the shocks that are on the LS. I could however, put small bolts through these holes and use a washer and a nut and the GSR bar would fit fine. At this point, I don't really think that this is necessary with the bar on it now being ok. So if anyone wants to do this on a car and wants the GSR bar, I'll sell it to you if you want it.
