[68SWB4x4]

I got some casting #s off a 10 bolt front. trying to figure out the gear ratio.... These are casting numbers from the underside of the pumpkin on the inside.

14030876
6
3

Are these the right numbers I think its an 8 but might be a 6 or a 3.

Thanks! if anyone has a website that I can look these up myself that would be great.
