Richmond gear is this a 3.73

[gwandro]

I’m trying to find a 3.73 rear end and need help identifying if this is a 3.73
The numbers on the gear are
Richmond N2 80-7858-1 8620

Count the number of teeth on the ring gear and divide by the number on the pinion.

That's the ratio.

Yes I know this but it’s one off marketplace so I’m just looking at pictures. Just seeing if anyone out there knows before I go and look for myself. Done research and I can’t find anything on the numbers. The truck it’s said to come out of should have had a 3.73 but you just never know. The person I’m talking to doesn’t know for sure what it is

Have the person you are talking to count the teeth on both gears. And or get us ALLL the numbers off the ring and pinion. Normal there will be a pair we can divide. Here's an example,the first numbers are the ring gear part number the last four are our teeth count in this case

3.73 should be 41 on the ring, 11 on the pinion (ie 11:41 or 41:11 as stamped in the gear).
