rear end interchange
Hi : Can anyone confirm if a 1A ( '51 Ford) 10 bolt pig will fit in my '54 Merc. The current one in the car, (a 4.10 ratio) looks externally identical to the 1A centre section ( a 3.90 ratio). Thanks : Bruce

Re: rear end interchange
Not positive but I remember hearing about different splines in the spider gears,to verify pull an axle and try it.

Re: rear end interchange
O.K. guys, just for the record, the 1A pig fits perfectly in my '54 Merc housing and even the axles interchange (same spline and length). As a bonus the 3.90 gives me a little less RPM at any given speed than the 4.10 and all the niose is gone. I found a Hemmings site that gives all the rear end data for all Fords and Mercs from '32 to '57. It showed that 49-'early '55 Fords were the same as '52-'54 Mercury. Thanks : Bruce

Re: rear end interchange
The 54-56 wagons had different rear so it will not fit those.That means that it will probably fit a 55 and 56 also (except wagons and Tbirds)
