90 ls needs new sway bar bushings

hey guys i have a 90 ls and the sway bar bushings are gone in it and im going to replace them but i dont know what to look for. im keeping the stock sway bars so just looking for replacement bushings. anyone one knows what good out thier? ive checked out the ES bushings but i got no clue what size my car has.

another question and its off the subject, last time i drove my car about 2mnths ago i noticed it keeped swerving to the right like it was hydroplanning and i got no clue what it might be. tires are still good. anyone knows anything?

Just changed mine out on my 90 GS 2 days ago. i did front and rear. here is what i ordered.
