I have had a long search for those elusive brackets to do the svt brake swap. and...I found them. You can order rebuilt calipers from Napa with the brackets. I got talking to the parts guy and for the cores he said he didn't care if the brackets were on the old ones or not. So for a total cost of 120$ I got refurbed rear calipers and svt brackets. YMMV with your store but from what I understand and what the parts guy told me they don't really check to make sure its exactly the same. So long as they get there caliper.
