New Bushing's

I am in the need for new bushing's!

You guys know what I mean, squeaky front end and rear from dried up rubber bushings.

I am looking here http://www.truckperformance.com/products/?searchtype=678d&sortorder=DAAAAA&productcategory=Bushings&category=Suspension+%26+Chassis&sf1=MAZDA&sf2=1993&sf3=B2200&sf4=Vehicle+Specific+Bushings&sf5=2wd

Everything is from energy suspension, but I'm lost, I don't know if I need two of everything.....? do I need to buy a pair of them all?
