go here to see what you are in for.

)
those three port pumps are red hot if you pick up a low enough mileage one.
the seals go before anything else. and next the brushes or wear on the commutator.
rest of it is built like a german brick shit house.
anything that has done less than 100,000 mi is worth a shot.
both i rebuilt were under 50k mi jobs.
barely worn. the seals had shit themselves that was all.
a crime almost to scrap them.
mad max in the apocalyptic desert speaking here, keeping things going.
