The suspension(?)/performance option on my car is WY5.
I measured the front stabilizer bar as 33 mm or 1.29 Measured rear bar as 23 mm or .91 "
Do those measurements seem correct? I am removing the stab bars to repaint & though might as well replace the bushings.

 

More or less correct. 32/23 were the usual actual values if memory serves.

Get poly bushings & end links. For the bushings, use the next smaller SAE size than the metric equivalent. Like, for 32mm, that works out to 1.259"; use 1-3/16" rather than 1¼" like would seem to be the right one. Use 7/8" for the 23. End links want to be about 2¼" or 2½", both front & rear; choose whatever length makes the "arms" of the bars sit level. You can get em from board sponsors, Summit/Jeg's, your local speed shop, or even the parts store on the corner might have em, usually in Energy Suspension.

You'll find that the bushings & links are probably the biggest bang for the buck improvement you can make to the car's feel. It's utterly astounding sometimes. Especially considering it's WAY under $100 for the whole enchilada. Next biggest bang/buck is rear springs & shocks; around $150 for the package and maybe an hour and a half of work, and again, you won't believe the difference.
