If converting from a 3/4 to 1/2 ton, what rear end will fit?

[REPO1]

I think I may convert this truck to 1/2 ton suspension. It is a factory C20 Custom Camper. So it has rear leaf springs. Can someone tell me what I should look for at the auto wrecker? I would consider a 10 bolt, 12 bolt, or even a Ford 9". Basically I need the width, drum to drum. I can easily cut off the spring perches and install new ones where required.


Thanks!
