Disc brakes

I will soon be ordering a new disc brake conversion kit for my 69 Cuda. I was wondering if you guys had input on which kit seems to work the best. I have priced Master Power, SSBC, and one other one and they seem to be close in price. I also figured it would not save me but a few hundred dollars to do a swap useing 73-76 parts by the time I was done so I decided to go with a new kit. I want to upgrade to the 4.5 pattern and large ball joints so I wanted to do the brakes and suspension all at once. Any input? Thanks Tom
