    Can anyone tell me what stuff I need to get to make the 4500 work with the Doubler?
    I could have sworn that the 32 spline, 400-version 203 was needed as along with the adaptor?

    If not, shed me some light and tell me what I need to scrounge for.

    You'll need a 203 gearbox (GM or Dodge), a 32 spline input gear for the 203, and a GM 4wd version NV4500 with the stock output housing.
    Easiest way to do this is drill the front face of the 203 gearbox to the round bolt pattern that's on the 4500 output housing, then they'll bolt up. You may have some minor work to do to make the bearing retainer on the 203 fit in the 4500 output housing, like clearance grinding for bolt head clearance, etc.
    Give us a call when you're ready to go or mention it when you order the Doubler and we my have a template for you to drill from.

    If you have a Dodge 23 spline NV4500 and a Dodge 23 spline NP203 they fit together almost perfectly. As Stephen said, you will need to drill the 203 and clearance for the bolts.
    This is what I currently own. However, Stephen also once said that I would be better with a GM 203 when I add the Doubler in my Dakota, using a Ford 205. I haven't asked him exactly why. Maybe it's for the extra strength of the 32 spline shafts, or maybe he's showing his anti-Mopar bias /forums/images/icons/smile.gif /forums/images/icons/wink.gif /forums/images/icons/laugh.gif ?

    I'm not sure either, but 32 vs. 23 may explain it.
