Mix 3.30 and a 3.31?

Dana 30 is listed as a 3.30 and the rear AMC 20 is a 3.31. Both will have a lock right locker, and it is a trail rig with no more than a few miles of rd at a time.
Anyone know if this will work without issue?

When matching gears they need to be with in .05

Example 5.38 in the front and 5.43 in the rear

Measure with a Micrometer
Cutter with an ax
Beat it to fit
Paint it to match
