Jlaa, your car has 2 pumps, 69608. The single-pump change didn't happen until late 1995 USA model year production.
I believe the other Bosch p/n is a "kit" which includes a 69608 pump and some electrical connectors you don't need.
OH, and note the letter before the numbers. B972328 is before C226335. I don't know why MB didn't just use 7 numerals...
