I have had a 47 Chevy Coupe built for 10 years now. The first time I did a Nova subframe but later redid the frame with a Mustang II. You are getting into a lot of work with a chassis swap. You are going to have to make body braces, radiator supports etc. The Mustang front ends are tried and true and will save you time and money. I used a Chassis Engineering rearend kit that was an easy install. Good Luck on your project!
