Yup. the soft top doors will work fine with a hard top. You just need to remove the door surrounds that attach to the roll bar, before you put the hard top on.
Heres a pic of my 97 with hard top and soft uppers.
Solman, I seriously thought you just swiped a picture of my jeep there and posted it. I have almost the exact same setup with a black '97 sport, tan hard top, black soft uppers with sliders, black wheels. Kinda freaked me out. The soft uppers with sliders works great with the hardtop.
If you want cheap hard doors look for some CJ7 or YJ doors they will work with a little bit of adjusting and minor fabrication. I have CJ7 doors on my TJ for the winter and trails. I think I paid $30 for the pair.
if you have the upper sliders, for 'most' intents and purposes they are considered full doors. Mine has the sliders and came w/hard top. i recently bought a soft top and went nuts trying to figure out which one i needed(top w/frame). Called rampage and they told me i needed the ST for full doors(door surrounds)-which i got. works fine.
