New 727 Cases

The press in sprague is fine. There are splines in mounts in and then the case is staked to retain it. When the sprague fails and it is knocked out of the case it breaks off little chunks of aluminum, so a new one cannot be staked in again. So the replacements are bolt in. The splines hold it from spinning out of the case, not the bolts.

I’d rather have a good original one instead of a bolt in.
