Small block in a slant 6 abody 67-72 cheap and easy using truck mounts

I can vouch for this. Did it a few years ago when swapping a 318 into an original /6 '70 Duster; used a mid '70's 318 truck bracket on the passenger side and a standard 318 A body bracket on the driver side. It dropped right onto the /6 K member, nice and level, plenty of room.
