Spool engine mounts. C-body VS B-boy

Is there a difference between 71 C-body 400/440 engine spool mounts and 73/74 charger engine spool mounts .
We have a 71 C-body 440 going into a 73 charger and it sits two high. I was going to pull the engine mounts off a 73 Roadrunner with a 400 from a cordoba and see if they are different.

Does the charger have a big block k-frame? If not, the motor will sit too high with any stock spool mounts.

Different K-members?? The charger was a orig 400 car that the 440 is being put into. So since it is a 400 car shouldn't the 440 sit down lower?

All passenger car big block spool mounts that I have seen are the same. I don't believe c-bodies got spools until 74, though.
