A body BB disc brake swap

Hi Guys...Thanks to everyone involved here as its a helpful site. I have a 69 Barracuda...bought a donor for the brake swap...75 Dodge Dart 318...easy swap I thought but my spindles are tilted forward now and I marked the a arms and spindles when I removed them from the donor car ds & ps. Also it seems that the wheels turn much sharper right than left. Any help will be appreciated. Thanks again for a great site...John
