Believe it or not, there really isn't many sizes of CV boots out there. The axle shop that worked on mine highly recommended Dorman but LittleBeast had bad luck with them. MechaTech seem to work fine for most people but you should be able to get some from a local auto parts store. Just measure the diameter of both the outer race & the shaft & when you go to the autoparts store, have them pull the one for a Trooper. If the 2 ends measure close enough, then you'll be fine.
