41dodge luxury liner rear axle

[Flatheadgasser]

Hi all trying to work out what rear axle ratio I have in my Dodge, there is numbers cast into the diff, have tried Google but can't find any information on it,  The casting numbers are 663473-18 

There is a square with a 6 and what looks like DD CD and on the other side on the snout there is a stamped 43 F.

Anybody got any ideas. 

Cheers Damon

It is 1:4.3.

on the axle carrier that bolt onto the housing, clean the very top of the carrier and there is a flat spot there, usually the ratio is expressed in tooth count here you may see something like 10/43 where you divide the smaller into the larger for the actual ratio.

This book....do you have one yet?.....says 4.3 to 1 ratio in 2 door sedans.
