i think they are 67 289 only. 67 convertible, 67-70 big block, 68 289 convertible, 68-70 302, 351W convertible
maybe add an imaginary line of what got trimmed off to better help id the upper hole distance.
more info from all stang forum.
http://www.allfordmustangs.com...seems 67 was one year only change.
of course thats the year i have. and also finding the rubber mounts are single year also.
i may opt for 68 units and make life easier and in my case, 1/2" higher.
This ain't no L-Kamino!
