well, they DO have to fit each other or the setup won't work
as long as you get SPRINGS for your prelude yr/model and STRUTS for your prelude yr/model, they will fit together

don't think you have to buy matching brands though. you will see, the spring slides over the strut. they are like, uhh, think of a telephone cord wrapped over a pencil.
sorry to have confused you....hope all is well. don't be embarrassed to ask questions....
later
