Yes, the 73-87 rearend is wider, but it's the perfect width for that 78 front suspension you're going to run because it's wider too.

As close as you're going to get is a 2.73 ratio. If you can live with that, the truck 12 bolt is perfect for your application. It's got the right bolt pattern and right width and is quite readily available.
