I take it those are the Shumaker conversion mounts going from slant 6 to a 318 on a slant 6 K member. For your Valiant Wagon.
Have also heard of people using the truck V8 mount on the passenger side and the slant 6 mount on the driver's side to put a V8 on a 6 cyl K member. You probably have some of those truck engine mounts there for a small block too.
Here is the passenger side V8 mount on a 360 going into the truck.
Can expand up the picture to get a better look at the mount.
