Gear Ratio Adapters

[lonchair]

Does anyone have a list that crosses IH gear ratio adaptors with stewart warner numbers? I am trying to route through all the old adapters we have in the shop and see which one I need for my terra.

I don't have that info, but these folks do:

I'm working a very similar deal right now, a speedo inna '56 s120 4x4 ambulance running an np201 transfer case.

Call 'em up! They even have an IH pickup in their "history" section on their website!
