Looking for an original A Body Dana LO23 or BO29 or Direct Connection

well, actually DC listed the 44,5" (#P3690147) and the 52,5" (#P3690007) Dana 60 Axle w Brakes in the 70´s. ´73 possibly, definitely in the´74 Catalog No SP5 (Special Parts)
We know Direct Connection was the result of what the Ramchargers had been doning for some time -developing performance parts for Chrysler.
Since the ´74 Catalog has No 5 it may indicate there were catalogs prior to that... and possibly also a 52,5" Dana, but if this shorter axel assembly was available in ´68...?
