Oh man I wish I did that. Drilling and grinding the firewall to match was time consuming.

The rear end selection is a balancing act. Know your transmission gearing. Make a flexible decision on wheel and tire combo... Then a target cruise RPM based on your goal of acceleration vs highway speed. At that point you can calculate what rear end gearing and width you'll need. You can order a custom rear end, but for readily available junkyard parts you may have to change a few decisions.
It may be sacraligeous but I'm running an explorer rear end in my truck. It's the right width for my wheels and the 3.73 ratio I needed to give me a comfortable RPM to cruise 75-80mph on the freeway.
