All the ones I've seen have been 4.10's. Both my '75's have 4.10's They're both K20's also. Hope that helped.

The ratio is stamped on the ring gear....all you have to do is pull the cover and write down all the numbers you see and post them here.....
Then you will KNOW for sure what the ratio is!
BTW -> I currently have two 14BFF's one has 4.10, and the other has 3.73
Military axles (CUCV) most commonly have 4.56s, I think.

i've also noticed that (2wd)trucks with the I-6 292 engine and sm465 tranny came with 4.56s. not certain if all but the ones that i've found do have the 4.56s
also 2 out of 3 K20 disels that i've run across came with 3.73s.

i found 4.10 locking in a 76 454 auto 3/4 ton even though stamping on axle tube said 3.73 - it was incorrect/false stamping, also i once had had a stamping code that said 4.10 on an '85 9.5" and I opened it up and it was actually 3.42....
