This is correct for 1968 and most 1969 428 Cobra Jet Mustang and Shelby's. However, in late 1969 Ford eliminated the Passenger side spacer and machined manifold differently which requires a different H pipe as well. For late version order part C9OZ-9430-1-BC for the Manifolds and D0ZZ-5246-D for the H-Pipe. Note that 1970 Shelby's were carry over 1969 so most will probably use early 1969 version. Will only fit 16 bolt 428 Cobra Jets Heads.
