. . There
are a lot of different pumps that Nissan used; more when
you add on the various aftermarket suppliers that once
existed. These are two of the bearings that Nissan used.
The 210-39 was predominately used on the early 65-67.5
and non USA 68-70 aluminum pumps. The 210-44 was found in
the cast iron pumps that Nissan used on the 1500 and
1600. All of the pumps and pump components are a
seemingly random event; production wise, so you'll have
to compare yours visually and check the measurements to
match up one of these. NOTE: The 210-44 bearing is not
corroded it has a hard grease coating.
