You'll have to change the entire axle for a 9-inch rear, you can get just about any gear ratio you desire for the 9-inch though. Posi units are easier to find for the 9-inch as well.
As I understand it (not a big 50's buff) the first year for the 9-inch was 1957. Someone correct me if I'm wrong. The 1957 9-inch will bolt right into your Maverick, but the 58-up are too wide.
Other 9-inches that will bolt up (and perhaps easier to find) are 65-66 Mustang 9", 1975-1980 Granada/Monarch 9", 1977-1980 Lincoln Versailles 9". It should be noted that the 9" was optional on all these cars so don't expect to find one in all of them. The 9" was the only rear in the 1957 Fords. -CP
: okay.. i basically understand gearing. you know.. 2.89's.. 3.55's blah blah blah... but what is this talk of "posi units" and such?? i am still learning allllll i can about cars, and this is something i'm not sure i get. Thanks..
: Jason.
: p.s. i heard any 9inch out of a mid 50's ford will bolt directly onto my 74 4dr.. this true? and how does "nine inch" and "3.55's" coincide. Thank you very much!!
