The Motorcraft MEOE16 inner TRE that I see on Rock Auto, is only $16.67 on Amazon. At that price, I'd get two there, except they show "Only 1 left in stock (more on the way)", so there may be a wait, but I bet that once they get more back in, the price will go up a lot. It does appear that they'll let you order two now to lock in that price.

That's what I'd do, but from the other options Rock Auto shows, I almost never buy anything in their "Economy" section so there's only three others left, Moog, ACDelco Pro, and Mevotech. The picture of the Mevotech is odd, no idea what they did with their design. The Moog costs over 50% more than the ACDelco Pro (which also has lifetime warranty)... so if in an hurry I'd get the ACDelco Pro but if you can wait, hands down the Motorcraft for $16 on Amazon if you order before the price goes back up.
Double check that part #, I don't know the relevant differences for an '02 Sport but that is a different part # than the inner TRE for some years of 2nd gen explorer.
