34. '67 had single exhaust (I think the 383 had dual, but not sure) 68 had dual exhaust.



383's had dual exhaust in 67, smaller diameter than in 68-9, though. See my post above.

Another way to put it is that 273's never got dual exhaust, and 340's never had single exhaust. 340's weren't available until 68, and 273's disappeared from Barracuda's after 67.

And of course non-hi-po engines had single exhaust all three years.

36. The reverse lights are different, '67 used the long style (I think) '68 had none (they were in the tail light) and '69 used a shorter style and a longer style, but I think they are different then the ones used in '67.



My 67 has the short style reverse lights.

37. The trunk lids are different, they have different emblem holes.
38. '67 trunk trim was 3-pieces, '68 was two, '69 was one
39. The tail lights are different for all 3 years



I only had to drill a couple of new holes in the trunk lid of my 67 to put 69 trunk trim and taillights on my 67. The trunk lid sheetmetal stampings are the same as near as I can tell.
