NP435 question

I have a NP435 married to a Dana 21 transfer case in my 71 f100 4x4. I want to bolt up a NP205 to my NP435. I know the outputshaft on my NP435 is a 10 spline and to bolt up the NP205 I need a 31 spline output shaft.Is that the only thing to do besides the intermediate adapter that I need to change? Is there a company that sells the 31 spline output shaft so I can do the swap?

You might need a different length drive shaft.

You have a 2WD NP435 in the F-100 with the Dana 21, if you want a married transfer case you need a NP435 from a 4x4 (think 1973-79 or F-250) to use with your bellhousing.
