Help w/ exhaust manifolds for '69 Dart

I want to put stock exhaust manifolds on my 360 into my '69 Dart. Does anybody know if these cast numbers will fit? 3614368 and 3418623
Does it matter if I have manual/power steering, manual/power brakes, column/floor shift?

I looked all over FABO and couldn't find an answer to this question, so I finally sent my first posting. Thanks for your help!
