Hi I have a 71 Custom Deluxe 4X4 1/2 Ton, it has 307 gears, (sucks), I want better pulling power, I heard you could swap later model diff housings (up to 87 as I remember), with little trouble, I remember being told one end was a direct bolt up and the other you had to change 2 brackets. This also gave better brakes & steering too. I'm after it for the better gears 4.10's at a minimum!

I think I got it fingered out

help is always welcome!!!

Thanks!!
