79 Bronco axle code H9??

3.55 limited slip. [confused]
No such thing as 3.55 gears for a 1979 Bronco...only 3.50's were available, but this ain't them.

H9 = Ford 9" Rear Axle / 4.11-1 / Limited Slip / 3,750 lb. Rear Axle Capacity.

H2 = Ford 9" Rear Axle / 3.50-1 / Limited Slip / 3,750 lb. Rear Axle Capacity.

Info source: 1973/79 Ford Passenger Car Parts Catalog / Bronco Rear Axle Ratio Codes / General Info Section, Page 41.

btw: 1959 thru today: If the AXLE code on the Warranty Plate (or Certification Label) begins with a letter: Limited Slip rear axle. If w/a number, no Limited Slip rear axle.
