Van LQ4/4L80E

[slotard]

My truck is a C20 so it has a 14FF that should be near impossible to break, I'd just like a posi of some sort (most likely a locker, that seems to be what's around) and 3.73s would work better for me than 4.10s. I'm pretty sure the 3/4 ton trucks of the era the van is have rear discs, don't know about the van. Doing spring perches and shock mounts isn't a problem for me, but I've never set up gears before, so the right deal on the right rear end is what I'm hoping for.
