I dug up all the numbers a few years ago. 91-92, flares were an option. I had numbers for front, non running board, and rears. At the time, I had my parts contact cross check my research and check availability and we could only get 3 of them. I seem to think that one of the rears were unobtainable. They also weren't cheap. IIRC, ~$450 for all 4. I ended up getting some old school "4x4" generic ones that I still haven't installed.
