Sportster drum brake ID, help??

[gettingreasy]

I got a backing plate for a sporster drum brake and was wondering what the differences are between the front and rear(both look very similar)? and weather a early backing plate can go on a later drum/hub? Thanks.

sportster and K-model rear brakes are the same from 1952 until at least 1977 that i know of.front brake was the same 1952 until about '64-5 when they got the full width unit which they kept until 1972.the best thing you can do with any front drum brake parts is sell or swap them to a resto guy or throw them away,they are JUNK! i speak from experience,i converted to disc on my '72 after i took out a little old lady's taillight with my knee-george

rear drum brake have a bigger inspection hole and are just as useless as the front ones. if any one needs i have 3 diffrent sporster fron ends with wheels stock , 6 over, 8 over all with 19" wheels. but only one set of tree's

Well it's a -64 casting number so it probaly is a front then. The shoes are about 1/2" wider than the rear I was looking at the other day. I want to use a drum so my bars aren't so cluddered with shit on the right side(it's foot clutch).
