Hot Rods Model A front end

Building a 1930 Model A coupe. Need recommendations in what front axle to use. I will go for 4" drop, should I go for 46" or 48" width? What steering?
Thanks, Per

 

With fenders? Might consider the shorter version made for fender cars to tuck the tires in further. I have that set up on my 31 coupe without fenders and will be changing it over to the longer axle as i feel it is too narrow for my application.
