Hank, here are the ratios for Dodge truck trannys.
540 OD shift patterns are different where 4th and 5th are swapped... 5th is up and 4th is down.
As far as I know a 12" clutch is the largest for the poly bell. Mine is drilled and tapped for 3, 4 and 5 speeds.
You can see there is not much difference between 2, 3 and 4th ratios of the 435 and 540, not as good of a granny ratio, but OD is a good thing
Gar
My ratios are the most common and are the first on the 540 list
