Anyone know what a 41407-52 brake drum fits? It appears to be a K/Sporty rear, but I can't find the number in my parts book. Definately a 7, not a 1.

That is a casting number, not a part number. They are not the same thing.

Thanks. I seem to regularly forget the distinction, and need reminding.

Now does anyone know whether a drum with that casting number might be the right one for a K/early Sporty?

I seem to recall seeing a raised -52 casting number on the very earliest, replaced by an indented number quite early on but can't recall for sure. Can anyone corroborate this? Later ones seemed to grow locating/lock tabs on the drum too?

I opened one up to find a nice set of original aluminum -52 brake shoes the other day - don't often see them it seems.
