I have searched the forums and can't seem to find what I need. I'm sure one of you gurus can help! I am rebuilding a 1999 F150. No door panel sticker to refer to, unfortunately. The front axle tag reads S976 B 355 88 9B25. Any help in decoding will be greatly appreciated.

Thanks,

Bob

 

8.8 axle with 3.55 reverse cut gears. not sure what the other info means. should be a 28 spline axle.

 

Thanks. Every little bit helps.
