73 Duster build named Fred

What, D60? I really like the 9” setup I have now. I can build a 4.88 third for the big tire setup and swap between big tire and small tire in less than an hour…. lol
I already have the d60...4.56 will do everything I need for a big tire, i meant back half the car.
But I do want to stick to the nostalgia look.
I have a 85 Turismo I will eventually get into in a couple years and do that big tire stuff to it, maybe by then a predator engine will be in my budget (winning mega millions lol) or some badass b1 ****.
