I used the kit plus the lines from Matt's classic bowties with my 14" rallys. about 700-800 bucks if I remember correctly. You will have to grind a bit off the top of the caliper bracket, about 1/16 inch. No biggy, bout 5 minutes each side and the set-up works great. I ran around with manual drums for years and the difference is like night and day...go disc, just my opinion, i'm sure others will chime in.
