Sorry about my delay. I am wanting to build my car to be streetable probably going to be more around the 400 hp range, but you just never know . I would like to put a 12 bolt posi into the car. Thoughts?

Not a new area, but I am rebuilding my 78 Formula Sunbird and I will need a strong rearend that can handle up to 600 horsepower. Additionally, I want to put on disc brakes. What are my options for a bolt in operation? Where are you located?
