http://www.monroe.com/assets/downloads/english/MonroeMountingLengthSpecifications.pdfLook up the Monroe shock for your application, find it in this book. Then record the compressed and extended lengths, and the end fittings used.
Then just start browsing through the book, I usually look for end match first, then length. When you find a match look up the Monroe number to find application.
I have not searched for shorter shocks, so I dont have any part numbers to offer.
I usually lift the cars and trucks I drive so I have to find longer shocks
