I have a weldtech pan in my 73 Duster with a 72 k frame (bought my mounts & headers before TTI came out with spool type.
I had to notch the k, but from the pictures on their site I think they have fixed this issue.

I had to do some grinding, but was able to use the structural cover in attaching to the 545RFE trans.
