    That's correct, they're only examples.

    Those are the correct types. eBay. There is a couple good YouTube videos on changing the drive gears. It’s not that hard once you see how it works.

    This has to be what I'm missing. When I pulled the old cable out there was nothing attached to it. This should be attached to cable right?

    This is what it looked like when I removed it.

    So if I dont have the original one to go off of color. How do I tell? My transmission is a 5speed and if I'm not mistaken the 85 f350 only had a 4speed? So I'm assuming it's a zf5 from a later model?

    Right. Trans shouldn’t matter. It’s rear gear and tire size. I’m 3.55 with “stock height” tires. Yellow drive gear, wine driven gear puts me on the money.

    I think you are going to be the yellow drive and yellow driven gear. Think that’s what my truck was originally. It was 4.10 when I bought it.

    I thought this was the style of gear a ZF5 uses, it's what comes up when searching. [​IMG]
