The lower mldg is the same " I think" from 1966 to 70 on B bodies regardless if vert, sedan / wagon or 2 door hardtop

its the sides I know for sure are different between 2 door hardtops versus sedans and wagons, 2 door hardtops are shorter , ( found it out the hard way )

The top mldg Im not 100% sure if its different between them or not
