Slick 60's

Try to make this simple. Can I use booster out of 65 in my 63, since 63 didnt have boosters? Can a dual master cylinder mount up to it? If I cant go this route has anyone mounted a later model, say 70's in their truck. Do factory holes in firewall line up or did you have to fabricate everything. I was hoping for easy direct bolt up. Thanks

im pretty sure the 70's MC will mount up, with just some rod modification. The info is on the site, but can't find it right now.
