So, I'm laying under my car (70 Cuda) contemplating on how I'm going to achieve the rim appearance I'm after when I go to different wheels, and after all is said and done the basic answer is I need a narrower diff. I "could" narrow the factory dana but I'm not really keen on that idea so I might shop for one already done at swap meets, online etc. My question is...is there a set width that people "commonly" narrow these things to or does everybody just wing it with a different number that they come up with for their car? (I'm sure of the answer I'd just like somebody to confirm my thoughts)
In my cars case, it's tubbed and the springs are moved inside of the rails so it looks like I could knock off 2" inches per side, but if I was shopping for one is there a width number that would be considered common.
I realize I can install a B-body diff but that doesn't seem like much gain for the cost or effort- but if that's what the answer is so be it.
