70 K member in a 66 Dart

Sorry for butting in, but I have a ?. If the k members are the same for a slant or v8, can I just buy stock v8 motor mounts for a swap from 6-8, or are conversion mounts necessary? I am under the impression I had to have schumacher mounts to do this. I havent had my 65 long and was thinking about a swap when the slant dies, which may be never as this thing runs so good. Thanks
