Mike B, that's cool.
The charts for Advance Design Big Trucks I have do not show that as an option. It shows a 53 2 ton could have 6.17:1 for a single speed and 6.13:1 and 8.10:1 for a two speed. This happens to be the ratios in my Art Deco truck for some reason. I guess knowing what is your truck is always a good start. These are available in the service manual, somebody posted about it being online somewhere.
Do you know which eaton pumpkins interchange? Will the pumpkin from a Task Force fit the really early stuff? Will the 60s eaton pumpkins fit? I'd love to get some slightly more usable gears.
