Do I Replace Strut Rod Bushing?

[914lps]

I have a 91 LS400 with about 120,000 Miles on it. Time to replace the struts. Front and rear. Still debating in my mind if I'll go with KYB lifetime at about $250.00 for all fout, or OEM at about $200.00 for all four. Locale guy will do the wrok with a new alinmemt for $250.00. But what I need help om is the bushings??? The ones I have are in O.K. shap, but should I just go ahead and put in new ones at this time???
