I do not yet have my axle under my sami yet

I'm currently waiting for my rear axle, which should be here on Friday!!

I'm am not sure when they stopped making Yj's with front leaf springs, i might of been 97.
You can call trail tough and they will give you all the info and possibly be able to sell you some springs.
The springs i got are out of a 94 YJ.
The front springs are a 5 pack, and the rear are 4.
You would just use them the same way that they were used in a Jeep, front to front and rear to rear. Some guys are using 6 spring packs all around, but i want flexy so i went with a lot less.
Here's a pic of mine

Sorry for the blurry pic, i can get a better one if you want me to.
Hope this helps you out, if you got any more questions feel free to lay em on me.
