B16 PV's around 1960 could have 4.10 or 4.56 back axles. If you can't find the small tag under one of the diff cover bolts the original ratio can be looked up in the parts book where they specify the ranges of chassis numbers for the two axles. You can also turn a rear wheel one turn and count the number of turns on the prop shaft. The difference will be a about half a turn of the prop.
