Will these fit the rear sway bar for a 95 ST?

I read that they're 16mm. And as far as putting them on, once the end links are off is it just of process of sliding the old ones off and sliding the new on? Or is there a slit to where they just clamp over the bar?

The bushings are split. I would recommend thoroughly cleaning the bar, as the grease provided with polyurethane bushings is very sticky and will pick up any contaminants it comes near. If you find it difficult to get the bracket back into place, a little brake grease can make the process easier without damaging the polyurethane. Don't use a petroleum-based lubricant.

Great, thank you for that information, that will help a lot. Now, will any 16mm rear bushings work for the stock sway bar?

Any universal one should work. Reusing the stock brackets is a different story. You're going to be better off using the brackets that usually are provided.

I personally purchased Prothane bushings with brackets for my rear one (GT 17mm)
