im pretty damn sure those mount work for those calipers, if youve got a free hour give him a call and he'll tell you everything you need to know. there is another company making some also that i KNOW work for those calipers but dont remember the name. Search for muchado on pirate he did a writeup on the swap
I run that systems. PM Toywelder on PBB for the info on the brackets. I'm very happy with my setup, stopping 38.5" SXs. I just got back from a snow run, which had us on a lot of icy blacktop to get to trails. Excellent brakes and good biasing.
Look in that pirate thread on page 4, for my setup. Note, that if you want to do things right, you need to look at your entire brake system: front to back biasing, master cyl size, booster size, etc. There are plenty of JY parts that bolt right in, so its not super costly. I probably have $200 into my entire system.
