Question Factory Gear Ratios for 80-86 9" Rear Broncos

Hi All,

What is the Standard rear-end ratio for 80-86 Broncos w/9" Rears?

I have 2 Bronco's w/9" rears and both have 3.50's I know that the 4.10's were an option.

Did Ford offer / install any other ratios in Broncos?

Since I am having a problem with my 9" rear in my Bronco see -->

I figured I might be able to get out of it cheap since my local bone-yard sells complete chucks for $100.
