Dodge/Chrysler 9-1/4 diff cover with FFS badging.
Does not work with 9.25 Front Axles!! The Differential cover is a 1 piece Plate steel cap 3/8" (.375") bent 8 ways then welded to a 3/8" ring! The fill plug is a generous 1" ID for easy fill and oil level check. After welding the mounting surface is machined absolutely flat for a perfect fit! For the REAR only!
