There a minor differences betwen the '67 & '68 mustang. Let me go through them all. The First thing is the Horse & Corral on the front. The '68 stang has an ugly flat chrome plated horse with no wings. The second difference is that "Mustang" writing on the front quarter panels is in script writing toward the doors instead of plain wrting under the mustang badges. The '67 has no reflectors on the rear quarters. Another difference is the leuvers behind the doors are present on the '67, but removed from the '68 model. These cars came in a few flavors. The first was the 200 cubic inch straight 6 cylinder with 195hp. The second was the 260 cubic inch; a hotter motor, but still nothing to boast about. Then you have the 289 which had about 225 horses. Then you have the 289 Hi-po with 271 horses. The 351 cubers and up to 429 Super cobra jet came in the illustrious fastback GT 350 & 500 models which today are worth more than $50,000 US in prime condition.
