47 Widsor Axle Ratio?

[grey beard]

I have access to a 47 Windsor parts car. Can someone tell me where to find the axle ratio stampings, or what ratio this vehicle might likely be? I am looking for a third member that will fit into my 48 B1B pickup that will be a longer ratio than the current 4:10.

Anyone need Windsor parts?

Thanks

It is on the hog head right side, on the flat machined area as most stampings are. Being a 47 Windsor, and if the diff has not been swapped, it will be highly likely it is a 3.54.................Fred

Fred,

I surely hope you are right. That's what I'm hoping for because that big a change would be worth the labor and time. And now, if I can just verify this and if it will interchage, there's my poor man's overdrive gear ratio I need to float along with freeway traffic. Thanks for the comeback.

Listed for 1946 to 1948 Chrysler C38 were 2 diff ratios, for the Windsor, usually it had the M5 trans and 3.54 rearend, the Royals had a 3spd fluid drive and a 3.90 rearend. But I suppose it could have been ordered from the factory either way, but not likely.Look what I found in my 47 parts coupe, which is a Windsor with a M5 trans, it had a 3.73 rearend, probably swapped in, but who knows, amybe it was ordered that way...............Fred

Sorry, but I have it already installed into my 47 Chrysler, how about a 4.31, probably not eh. I can look around for one for you if you like.
