I can decode it for you, but I think you'll find that to be S424E instead of "F"

S424F is a 1989 NUMBER...........The S stands for Sterling plant. S is just a prefix number. F is a suffix number. Most 8.8's were produced by the Sterling axle Plant. The few that were not came from the Van Dyke plant

3.27.......gear ratio

A88...........The A should stand for 1 which is non limited slip differential. The 88 is 8.8 rear

7E18............. is the date your rearend was built. May 18, 1987.

424F is listed under the year 1989, but your rearend was built in 1987. According to the book, that number should read S424E.....for 1987. That would put everything smack dead on.

424F, and 424E however, both fall under 327C2. 3.27 is your gear ratio. C2 is the code for a non limited slip diff.

S424F is from an '87 Lincoln Continental/'87-'97 Lincoln Mark VII.

The "A" before the "88" does not mean non-limited slip. That letter is on tags from limited slip rears. Sometimes it's not on tags ata all, whether they be limited slip or non-limited. Sometimes it's after the ring gear diameter instead of before it.

Hate to bump this.

New axle from a '10+ car.

V237-R on the main axle tube sticker/decal.

Barcode on the diff cover reads:

V237R061390209J0

Also have a number series. The Alpha-numeric pair is on "top" with the character "below".

D14/Y, E46/A, E28/B, E12/B, E64/A, D15/Q

Any help as to what this assembly was originally would be appreciated.

It now contains a 3.73 gear set, which should be OEM, trying to verify it's origins.

Thanks!

The "L" in 2L73 denotes it as being equipped with a T-lok (limited slip) carrier.

3.73 is a good ratio.
When doing a gear swap it is highly recommended to rebuild the limited slip carrier. The part number from Ford Racing is M-4700-C for an upgraded clutch pack kit.
