Try a JC Whitney mag. Lots of good stuff
Quadratec Jeep Essentials. Quadratec.com they're pretty good too.
I have a 1991 YJ Sahara also. I completely rebuilt mine about 8 years ago. I got parts from almost everywhere, there are so many suppliers it will make your head spin. Quadratec.com and 4WD.com are probably the biggest, but look on Ebay, Acmejeepparts.com, buy you self some issues of JP magazine. I sure you will find what you need and then some. Its the beauty of a jeep that there are so many people that make things for it.
