rear end gear ratio question

I found a dana 30 for sale and would like to have a spare. Its out of an 86 cj 4 cly, I dont know if its stick or auto. What gear ratio would it have in it? I know most yj 4 cly had 4.10, i was hoping that cj'c would be the same. If so I would just have to buy 4.10 gears for my rear. Thanks

That's a wive's tale that most 4-cyl had the 4.10s. They could have either 3.55s or 4.10s and there's nothing more than internet rumors to support one ratio being a greater number than the other.
