I have a 91 b2200 with 5spd I wondering what the rear end ratio was, and I see a cable that goes into the front of the rear end what is that for?

My rear end in my truck was a 3:91

Not too bad.

I havn't ripped mine appart yet to find out. I've heard the US versions run 4.44 but I've heard a lot of ppl say 3.91. So I would guess its going to be one of the two depending on where the truck was made.
