Carolina's method has worked for me for years at least in ballpark ,you can tell a 4.56 from a 3.00 mabey not a 308 /300 also early Fords mostly wagons were marked between the reinforcing ribs a large P or an N the n meant nodular iron,which is much stronger ,most but noy all marked with a p were limited slip,ddont know how yo id Detroit locker fron outside used in late sixties early 70s probably wont find one of these anyway also a 9 in you cannot get a socket an bottom bolt the others you can
