When the new body style came out in '04, Ford continued to produce the old (curvy) body style as the "F-150 Heritage". For the '04 new body style, there were no V6's or manual trannys offered, if my memory serves me correct. However, in an '04 Heritage (old body style) you could still get a V6, and a manual, but only in 2WD. I believe the '05 new body style will have manuals, V6's, and manual V6 4x4's. The Heritage is not available for '05.
