Ok, here is the 411.
To my knowledge no one makes correct 1967 engine mounts. They say that they do, but what they supply is 1968-70 small block mounts that only work with 1968-70 small block frame stands.
1967 frame stands are the same small block to big block. Starting in 1968 until 1970, Ford changed frame stands for the small block V-8's, but only in non-convertibles. Convertibles used the big block frame stands. Why? because supposedly the big block frame stands allowed the engine to sit slightly lower for a lower center of gravity. The convertible engine mounts are not reproduced either. They may have the same Ford part number as 1967 289 engine mounts, if you can find NOS.
