I guess I should be a little more specific.. Will the center section or ring gear fit from an A520 into an A523?

Don't know about the gear, but the cables will be different.

Thanks Bob. Any idea where I could find such info?

The short answer: yes and no... It depends upon what your trying to do ? and what year the transmissions are ?

Some parts can be swapped around, others are very much limited because of several running changes that New-Process did over the production life of the 520 and 523.

The shifting forks/shifting mechanism and the front pinion shaft bearing are the two primary differences between them from a technical standpoint.
