Engine torque strap

Professor Fate said

I fail to see the need for a torque strap on a spool mount K frame, since it cannot separate, even if by some fluke it would fail- if you just need to minimize engine movement, install poly bushings.

I had a 1971 340 Duster and I have broken my share of motor mounts. so with the type of Motor mounts on a 1974 does not have the same issue? If not needed I can save money by leaving it as is, or getting the polyurethane motor mount inserts. This is my first time owning a 1974 Duster with a 360 magnum swap. Please let me know.
