if the labels have been wiped off the only real external difference
between the earlier and the later starter is the length of the stud on the
solenoid. usually  longer on the later model

the SR401 (2.1) has a higher horsepower rating by about 25 percent.

Also i just checked some listings and now only find the SR19 starter from
1981 thru the   1.9 engine.  so only three starters now instead of four.
