Will these headers fit?

Yeah, I coulda been more specific.
The 453s fit just about every Mopar model, a few exceptions, and the manufacturer got vague when they went to transverse bars and spool mounts, - I generalized cuz I work on all models.

I have the spool type motor mounts, but I don't know what difference that makes. Maybe that's the mystery?
I don't want to make a $1000 mistake.
