Kelsey Hayes Disk Swap
I second Matt's sugestion. I installed a set of SSBC last spring. I wanted stock appearance (look similar to stock KH). SSBC rotors are drilled and studded for both 5x4 and 5x4.5, so I could retain my my sbp wheels.
If sbp and stock look are not a priority there are several complete kits available. Wilwood, MP, and others advertised all over. Not sure but I have heard that some kits may change the cars front track (moves the front wheels out slightly "wider stance"). Call the the kit manufacturers before you decide.
I would buy a complete kit. I don't think you will save anything buying parts piecemeal, when you consider time, research, aggravation and rework. All I needed in addition to the SSBC kit was brake fluid and 5 RH lug nuts.
Lastly I almost waited to long to install Disks on my car (due to wanting to retain stock look). I don't care to argue with any any one about this, but with drum brakes and a stock motor these cars are not safe in unpredictable traffic. This is not saying that with a good driver these cars can't stop, They can't stop like today's rollerskates with 4 wheel disks, when the idiot driver slams on the brakes in front of you while he is texting.
Never mind with a modified drivetrain.
Hi Matt, hows it going?
