shocks for ss springs

i got rancho 9 way shocks from a ford bronco from rock auto

Best thing is to measure shock length with the rear hanging and shocks removed. Center to center on the mount post and add an inch. The extended length is more important than the compressed side. Really don't want the shock being your limiter on either end.

I think there are 3 base numbers with compressed and extended lengths:
99113 - 13.280 20.030
99114 - 15.410 24.290
99116 - 15.140 23.750

I cant remember which one i went with, but i may have the box kicking around with the part number on it, if i remember to look at it.
