Wilwood brakes for my Dart

A buddy of mine decided to go strut front end on his 70 Duster, so I bought his Wilwood set up for my 73 Dart Sport. I was curious as to what master cylinder to run with the Wilwoods? I would like to use the aluminum bodied Mopar master cyl., but not sure which one to use. They are 4 wheel disc, manual set up. Should I also bypass the orignal proportioning valve, and just use an adjustable vavle to the rears? Any help would be great appreciated. Thanks.
