rear end ratio difference

I have an 86 F250 4x4 with a 460. 4spd and a 3.54 Front and 3.55 REAR axle.
The rear axle need to be replaced, I have a 3.54 rear axle from a 84 F250 4x4. It came witrh a 460 C6 auto.
Am I going to run into ratio problems using matched axles? I don't think so. but I was surprised to see a 3.55 ratio there originally?
Is it because of the auto trans vs. 4 spd difference?
Want to know before I proceed with a swap out.....

thanks

It will work fine, the 0.01 difference is due to the difference in axles (i.e. Dana 60, ford 9" Dana 44, Etc.)

I would agree. When we use 4WD we are not on dry pavement .I remeber fors having 4.10/4.11 combos too.
