Typically, you will need:
1) type of mount at each end of the shock (threaded shaft, round bushing, etc)
2) shock length at full compression
3) shock length at full extension
If you call Rancho, they may be able to figure it out without you needing to remove it for the measurements (for example, they may know which shock it is by visual construction details of the shock along with the diameter).

^^^ This!
Any shock manufacturer can, and any parts store SHOULD be able to get you something based on this information. I remember spec'ing shocks based on this info for custom suspension setups for offroad using books. Page after page, looking at the compressed and extended measurements trying to find something that would fit.
