-    * 57-e58 baseline pump that all others came from. no oil seal. uses a snap ring and a full profile woodruff key at scavenge gear.  +
-    * L58-59 same as above but now has body machined for a oil seal. +
-    * 60-e62 same as L58-59 but the retaining ring at the scavenge is replaced by half moon retainers. The scavenge drive gear is counter-bored for these half moons and the woodruff key is shortened so it won't interfere with the half moons.+

-    * A plug is put in this new hole if body got used on a style1 case set.
