Backhalving?
It is your car so make it how you want it. You have gotten some excellent opinions both ways so you have to decide what fits you. I have never built a car with much concern for selling it. I get concerned with my enjoyment and the quality of the build. I have a full chassis Pro Street car. I am building a back-half Pro Street '65 Mustang for my daughter, Sarah. I am also building a back-half '33 Chevy 2-door sedan Pro Street for my wife. Personally, I like that look with wall to wall meats under the back and the only thing you see between them is a chrome Dana 60 cover! People are asking me all the time to light the tires on my Demon but I just don't do it. Like the man said, how often do you want to spend $600 plus for big Mickeys!
I helped a friend on the other hand with his Scamp. We moved the springs in and mini tubbed it. I narrowed an 8 3/4 for him with B-body brakes. We had Jamie Frankland shorten and respline stock axles. He now has 10" Cragars on the back. It looks really good too with the 295 50 15s under it! It hooks really great using just an adjustable pinion snubber and it's a 4-speed!
Back-halfing a car is serious work and requires special skills in fabrication, welding, tools/equipment and .......measurement!
Have fun making your car the way you want it to be.
