This is a set of 3.73 gears that was removed from a 12 bolt rearend out of a
1969 Camaro Z28.
They show part number GM 3862525 11 41 6 69 - on the Ring gear
and GM 3862513 11 41 5 69 - on the Pinion gear.
These are dated for any car built after June of 1969.
Great for that part number correct restoration.
