I don't think anyone will be able to read those numbers. You would have to type them in by hand or take clearer pictures.
If all you care about is the ratio then just turn one of the stub axles one complete rotation and count how many times the pinion turns. If it turns 2 and 3/4 times its a 273 if it turns 3 1/2 times its a 355 and so on. (This only works on posi rears that are still together there is a different way for open rears but we dont care about that here.).

Just count the number of teeth on the ring, then count the teeth on the pinion, and divide the larger number by the smaller number. It's not rocket surgery.
