help identifing (ford motorsport ring & pinion?)


I bought some 373 gears from someone on ebay and was told they were ford gears they are new but no box, does anyone know what markings should be on them or any other way to tell them apart from another brand? Any help would be appreciated!

Okay, brand new in the box FRPP 3.73 gears: On the bottom of the pinion gear is stamped: 373 1L5LA M7I

On the back side of the ring gear it states: 373... Then 1/3 way around the ring gear: 1L2-D9...Then another 1/3 way around the ring gear: 07-21

Hope this helps
