3 front and 2 rear seems to be the norm.

As fas as exposed shaft from the shock body to the shock eyelet and correct me if i am wrong but i think the above measurements are not correct.

3 limiters front = .090" which converts to 2.286mm which you would subtract from 21mm of the given shock shaft stroke which comes out to 18.714mm

Front with 3 limiters equals 18.714mm of exposed shaft

Rear with 2 limiters equals 25.976mm of exposed shaft

I corrected my shocks last night since i did not have my shock rod ends turned in far enough and it was a night and day difference.
