Thanked 10 Times in 9 Posts

There were NO 9 inch rears installed by FOMOCO into 69 Falcons I am told. To check your car........if you can put a socket on the bottom center section is a 8 incher.

This has been mentioned many times here in previous post. It is a old junk yard trick.

This is a 9 inch, 31 spline, Detroit Locker with 3.50 gears.

Some folks believe you can tell spline count by looking at the ends of the axle where the brake drums go. I have read this also on the Web. I have found it is not 100 percent accurate.
