360 flex plate
The six cylinder used a different flexplate and the Hemi had an 8 bolt plate.
Some of the 67 and down flexplates had a smaller pilot (center hole).
Other than that from 68 into the 80s all mopar v8s used one of two factory flexplates. ALL 6 BOLT CRANKS HAD THE SAME BOLT CIRCLE! If you keep the two (10 inch and 11 inch measured diagonally across the converter bolt holes) in the shop you will always have the correct one for a 904 or 727 transmission. Also note that in some cases a 904 and a 727 use the same flexplate. You either had a 10 inch converter (smallplate) or an 11 inch converter (large plate)
