4 speed or automatic?
The four speeds have a small "bullet" that the speedo cable screws on to. There are two seals on the bullet. One "o-ring" on the outside of the bullet to seal it to the trans case, and one lip type seal in the inside, to seal the bullet to the speedo gear. Either one(or both) could be leaking. The bullet is held to the trans with a small clip, as you say, and there is a 7/16" head bolt that holds the clip. You can loosen the bolt, and slide the clip around to remove the bullet, but first unscrew the cable. The speedo gear will come out with the bullet. From there, you can replace both the o-ring, and the lip seal, and then reassemble.
The 350 automatic has a similar bullet, but it will be aluminuminum, instead of steel. The steel bullets usually have a metal-clad inner seal, while the aluminuminum bullets use a plain rubber seal. Both are replaceable.
The 400 automatic has a different housing, but the removal is basically the same, the inner seal is the same, but the outer o-ring is a larger diameter.
btw...most 4 speeds have a 90 degree adapter that the speedo cable screws onto, then the adapter screws onto the bullet. The seal replacement is the same, regardless.
