Rear strut mount bushings

[32ValveGuy]

Hello Guys.The previous owner of my 1990Z replaced the rear shocks with Bilstein non-adjustable ones since he could not find FX3 replacements. The shocks have about 2,000 miles on them so they are fairly new. I just received a new pair FX3 replacement shocks and was wondering if I can use the strut mount bushings installed with the non-adjustable ones being used on the car? This is my first time messing with this suspension.

Thanks Joel
