Believe they are B-Body only.

Mysterious subject. Some cars got the Talls, some the Shorts. I've had two cars side by side, same year, same engines, one had the Tall Mounts the other the Short Mounts.

I believe it depends on what Motor Mount is used, but maybe someone can jump in with more info on it.

I do know that the Tall Mounts are more common than the Shorts. I ran out of Shorts many years ago, but still have some Talls left.
