    Hey everyone, noob here. My rear diff just went, was leaking oil and seized up, so I need a new one. It had B03A in it, which looks to be 4.10 gears. MY truck is a V6. I'm assuming it doesn't matter if I find the same diff that came out of a 4 cylinder auto truck? Thanks in advance!

    According to the op, 4.30 is right. My 02 2.7 manual 4x4 has the same.
