If it has the AEG151 casting on it...then it is a 1071.

My records here are not complete, but according to what I do have, it appears that there wasn't a Cross Drilled Factory Crank made for the 970 or the 1071.
Can anyone confirm this?
That said, I also don't have a listing for an AEG1053 Crank either.
