Don't expect much here due to these units being obsolete for so long, and parts also being obsolete for so long. Buy a nice rebuilt E-46 to replace these.
Quite possibly the most popular plow pump ever just because of the long run they had from late 1973 - 2005.
The E-57 had a short run from 2001 - 2007. Most of the E-58H is identical except the PA Block.
The E-58H came out in 2007 and replaced the E-47, E-57, and E-60 for all straight blades.
The E-60 debuted in 1991 and was discontinued in 2009. It was briefly replaced by the E-61H.
This was a short lived unit used to operate the EZ Vector V Plow which was also short lived.
The E-68 was an updated version of the E-88 (I know the numbers go backwards) used to operate the Xpress Plow.
The V-68H was used to operate the Meyer Super V Plows. It was quickly replaced by the V-70 Hydraulic unit.
The E-70 was used to operate the Aggressor plows. It was an option for trucks that did not have central hydraulics to operate the plow. These units are rare to see.
The V-70 is the standard hydraulic unit to operate the standard Meyer Super V Plows. It replaced the V-68H.
The V-71 is used ONLY on the Super VLD 7.5' plows.
Originally released as an upgrade to operate straight blades in 2010, in 2014 it because the standard hydraulic unit used on all Meyer straight blades.
This unit was originally used to wirelessly control the Xpress Plow. It was quickly upgraded to the E-68.
