I checked out the remanufactured sets and they seem to be a pretty good deal. It took me a minute to figure out which were the 26mm version, but I've got it now.
Part numbers for the aluminum A1CARDONE reman calipers are:
26mm front left: 19-1398
26mm front right: 19-1397
30mm front left: 19-1400
30mm front right: 19-1399
The 30mm caliper is simply the 26mm caliper but with a metal spacer between the two halves. That's the way to tell them apart.


They are available from Summit Racing and Rock Auto for 50-60 bucks per caliper + 35 core charge. Not bad at all. Just search for the part numbers and you'll find them.
Hope that helps!
