I wouldn't worry too much about the brass vs. plastic cage on the ball
bearings.
The key info is the 7303 and 7205 part numbers to get the proper ID and
OD,
the suffixes relate to special features.
In case you want the tapered roller conversion, Timken lists the part
numbers
on their automotive application web site as:
30205M Inner
30303 Outer
These are more sensitive to proper preload than the ball bearings.
In both cases the seal P/N is 471192
