Correct, the mounts from dodge from 12v to 24v are different. But, mounts from a 12v will bolt on a 24v in a conversion. You just use the front 4 holes instead of all 6. With that said, the 24v mounts will bolt on a 12v block as well just using the front 4 bolt holes. If you'd like pics I can dig out my auto world 12v mounts and bolt them to a 24v block. My wife's excursion has 12v mounts on a 24v storm block.

1st gen and 2nd gen dodge pickups are not the same.
Med duty, heavy duty, industrial have many different styles as well.

Correct as well. The oem mounts are not the same. But, the blocks are all the same. You can take an industrial 12v block and put it in a dodge. You can do the same with a 24v. Cummins incorporated all the holes in their castings due to production costs of several different casting designs.
