they both take the same pistons and barrels..
it's the longer  stroke that makes it a 2.1

hey Scott Doing some more checking yes there is a difference in the strokes
 on the cranks.   You can tell by measuring the space between one rod
journel and the next rod journel beside it .2.1L is longer.  also some of  the
stampings seem to be on different places between the 2.  What was  fooling me
was that somebody had put a 1.9L crank in a 2.1L  case.    It would be nice
if they had part # on them.   later  mark d
