50 Ford Rearend Question

I am using An 8BA and the rear out of a 50 Ford. The car had the three peed ****** with overdrive. Can someone clue in this dumb-*** shade tree knuckle-buster as to what the rear ratio is? MERRY CHRISTMAS TO ALL YOU HAMBERS. Almost forgot, went to Draglinks XMAS party and meet some real nice folks. Meet Swiss Mike and he was kind enough to answer some of my drunk *** flatty questions. Thanks. WHEN MEN WERE MEN AND CARS WERE STEEL, HO,HO,HO!

 

Most of the '50 od fords had the 4:11 rear. Sparky

 

Jalopy 43 is right. Unless someone's swapped out the 3rd member. The O.D. cars had 4.11's.
