Front ends should more realistically be labeled as
55 - 62
While not all 63's are of the "only" type most are.
Lets break it down.
55 -62 have small link pins and big snout brakes
9 times out of 10 these brakes will NOT work with after market wheels
63 only have small link pins and later flat brakes
Early 63's use the 55 - 62 style spindles / brakes
64 - 67 have big link pins and later flat brakes.
The snout is the easiest way to tell what brakes you are dealing with. Another is the way the grease caps fits.
Early - The cap goes in to the drum
Late - The cap fits over the drum with a lip to pop it off.
