in 1969 you can get RPO 4:10 gears but needed a COPO to get 4:56 or 4:88 for Camaro and Chevelle

For Nova you needed a COPO to get 4:10

Im not sure for Biscayne

you have to check the Power Team Chart

The axle stamp is gone as it has had ladder bars welded on and later removed and welds ground down.

I don't think this has anything to do with the gears as I have seen another Flint built L72 M22 4.10 Biscayne with nothing in the COPO F & SO boxes on the seat tag.

Thanks
