quick ford 9 question

what is the axle tube diamiter on a Ford 9" from a 76 f-150?
i need to order some perches as well as ubolts and plates - and my axle is sadly in another state, otherwise i would measure.

if anyone knows off the top of thier head, please let me know.

all my searching leads me to believe 3.25" but wanted to confirm

thanks

The tube on My '77 Early Bronco is 3.25.
