Motor mount question for magnum engine swaps

This question is for those who have actually done a 5.2 magnum motor swap-

Is the drivers motor mount different?

I have a 95 5.2 in the garage and compared it to a 273 and where the mount mount attaches to the block they are the same.

There was an impression that the 5.2 and 5.9 shared the same block lugs but I'm not so sure based on what I have here.

Can anone else chime in? I'm planning on a weekend swap and want to have everything I need onhand when the deal goes down.

Vehicle the magum is going in is 1974 Duster with spool mounts.
