If you have the space under the hood, a 7" or 8" single or dual diaphram booster is very common to utilize. They have 4 mounting studs and you will have to reinforce the inside of the firewall most likely. You can then use an early 80's style Corvette master cylinder. They are available in 1" and 1 1/8" bore diameter's which are the most common. Add an adjustable proportioning valve in the rear line and you are good to go.
The job requires a bit of fab work, but if you have the space it is very do-able.
