I forgot to measure it last night and need to pick up a socket on my way home from work.

What size is the rear output yoke nut on a NP205?

I want to say 1 1/8. I just regeared a 12 bolt last night and I'm pretty sure the flange is the same size bolt and that's what was on it.

Nope its bigger! My socket set goes up to 1 1/8" and it was way to small. Then I got side tracked and forgot to measure it <IMG SRC="smilies/rolleyes.gif" border="0">

i am almost sure it is 1 5/16.....

yup 1 1/8 for the 12 bolt pinion nut and 1 5/16 for the 205 yoke.
