If you go to the manufacturer's online they have a section (or did) that did show you the mounting structure for each end. sizes etc. what length is requireed. you have to find a page like this;
http://www.monroe.com/catalog/documents/08_MountingLengthSheet.pdf . you have to look to find these pages as usually they first ask for application and then you get lost. I am going to give you a few links that will lead to a page like the one above.
1-google -monroe and it gave me this link-http://www.shockshopusa.com./index.html and then clicked on s/absorber mountings, then click on the monroe icon and then click omn mounting and length sheets and you will find what will fit yours by dimension.
most manufacturers have these listings
I went with rancho 5,000's for my K910 and found them that way. I would have to dig back for the nbrs. rancho's were once listed under monroe but are seperate now. most of the manuf. have 800 nbrs , you can give them the partiiculars and let them research it for you
