Harold,
Got all from ABS... front, rear, and master cylinder. Not sure about the calliper mount. I would like less pieces, but it is stout. As for service, they were great.
The rear is not a kit they market (for 46), but they contacted me numerous times asking for measurments etc. Only mod required by me was drilled two holes from 3/8 to 1/2 inch on the lower spindles on front. The rear was a bolt on. I have pictures of the complete install. All of those were just mock up/fit.
