To answer your first question. Pump gears(for the 904) are the same from 1960-2003 for the lug type converter. In 1993 they also had a milled flat converter hub(no slots).
From the photo, the painted converter looks like a 904 converter and the unpainted one a 727. I say that, as the hubs, at least to me, appear to to be different in diameter. Measure the hubs, and the one with the smaller diameter would be the 904 converter. Again, I can't tell from the photo, but the the purple converter could be a lockup style as Chrysler had both lockup and non lockup transmissions in their cars .
