Hi, I have a '97 Civic DX (HB) and was wondering from what models can I use sway bars.

Could I use a '95 EX rear (13mm) sway bar
and a '99-'00 Si/EX/LX front sway bar?

 

For the rear you can use gsr, civic, or type r swaybar. Your control arms have the hole for the sawbar already, but you will have to drill a second hole for the rear swaybar to mount to the chassis. Another option you have is purchasing a bolt on kit with swaybar for the rear like progress, or srr. For the front you will need to replace your lower control arms, best one to use is a 99-00 si control arms, they are a stronger than ex control arms.

 

And dude, its swaybars! not say bars.
