Default Gear ID Help
I did a quik search but came up with nothing.
I changed the diff fluid today in my '93 notch and while I was there I tried to ID what gears I have. I didn't see anything on the gears but this is what is on the metal tag bolted to the cover:
S215C
2L73 88 2M01

Thanks.
That's what I was afraid of. I didn't know Ford put those gears in 5.0's. I just wish they would of at least been 3.08's which is what came stock in my old '92 GT.

count the number of teeth on the gear and then divide that by the number on the pinion

I looked on the ring gear but the ratio was covered up. Didn't think about looking on the pinion.

By the looks of the diff cover, I doubt it.
