F50 UAS question

i kinda understand how the fronts will be done but the rears on my f50 have the spring and strut separate. 

which air bag spring will work from their choices [url]https://www.universalairsuspension.com/index.php?cPath=25&osCsid=d13035bcc0db1215e2d372ab8467a94c[/url] ?

havent really been able to find the answer in my research. im sure i'll need a bracket for the rear also. any help with that one also? :biggthumpup:

seems like my research keeps pointing towards air runner
