Rear shock length

I just went out and looked under my car for ya and I have rancho 9000 part number RS999180. I am running Caltracs with one inch lower split monoleafs. These have Eyelets that are bigger than stock but this is a easy fix with a bushing. Here is the specs per rancho website. RS999180 Compression height 14.125 Extension length 21.125. Hope this helps. Here is a link to the specs of rancho, go to page 7 for 9000's.
