Looking for 360 engine mounts

I’m in search of a set of 360 engine mounts for my sons magnum swap into his 67 Dart. I need the style for a 67-72 k frame, not the spool mount ones. Any help would be appreciated.

while searching on this website I came across someone selling 70’s truck 360 mounts and said they could be used to put a magnum in an a body without using the rubber do they would be solid mounts? Anyone done this. If so, is it recommended?
Thanks
